Opis:
In this work, a mid infrared thermography was used to study thermal behavior of solid oxide fuel cell (SOFC) with a circular shape and a diameter of 90 mm. The emissivity of the anodic surface of the fuel cell was determined to be from 0.95 to 0.46 in the temperature range 550-1200 K and the profile and temperature distribution of the anodic surface of the unloaded cell was given. The surface temperature of the cell was determined during operation and the polarity changes from open circuit voltage (OCV) to 0.0 V. It was found that the cell self-heating effect decreases with increasing temperature of the cell.

Opis:
This study presents a thermodynamic Aspen simulation model for Solid Oxide Fuel Cells, SOFCs, based power generation system. In the first step, a steady-state SOFCs system model was developed. The model includes the electrochemistry and the diffusion phenomena. The electrochemical model gives good agreement with experimental data in a wide operating range. Then, a parametric study has been conducted to estimate effects of the oxygen to carbon ratio, O/C, on reformer temperature, fuel cell temperature, fuel utilization, overall fuel cell performance, and the results are discussed in this paper. In the second step, a dynamic analysis of SOFCs characteristic has been developed. The aim of dynamic modelling was to find the response of the system against the fuel utilization and the O/C ratio variations. From the simulations, it was concluded that both developed models in the steady and dynamic state were reasonably accurate and can be used for system level optimization studies of the SOFC based power generation system.

Opis:
The aim of this study was to highlight the interest of using CFD technique as a diagnostic tool of a malfunctioning Solid Oxide Fuel Cells. Hydrogen starvation of a SOFC due to nitrogen dilution is one of the cell dysfunctions and can lead to its degradation. Identification of the starvation point allows to improve cell performance and establish the best conditions for degradation tests. To illustrate a potential of the CFD tool, several simulations of a single planar SOFC and its behaviour under hydrogen starvation were performed and analysed. The results showed that at lower cell voltage values of 0.3 and 0.5 V significant gradients in the electric current were noticed due to a local reduction in hydrogen concentration. The CFD analysis allowed defining desirable mass flow rate of hydrogen to SOFCs to avoid fuel starvation. The model constitutes a helpful tool for optimizing cell design and operational conditions.

Opis:
Mixed ionic and electronic conducting K2NiF4-type oxide, Nd2Ni1-xCuxO4+δ (x=0~1) powders were synthesized by solid state reaction technique and solid oxide fuel cells consisting of a Nd2Ni1-xCuxO4+δ cathode, a Ni-YSZ anode and ScSZ as an electrolyte were fabricated. The effect of copper substitution for nickel on the electrical and electrochemical properties was examined. Small amount of copper doping (x=0.2) resulted in the increased electrical conductivity and decreased polarization resistance. It appears that this phenomenon was associated with the high mean valence of nickel and copper and the resulting excess oxygen (δ). It was found that power densities of the cell with the Nd2Ni1-xCuxO4+δ (x=0.1 and 0.2) cathode were higher than that of the cell with theNd2NiO4+δ cathode.

Opis:
The perspective of nuclear energy development in the near future imposes a new challenge on a number of sciences over the world. For years, the European Commission (EC) has sponsored scientific activities through the framework programmes (FP). The lead-cooled fast reactor (LFR) development in the European Union (EU) has been carried out within European lead-cooled system (ELSY) project of the 6th FP of EURATOM. This paper concerns the reactor core neutronic and burn-up design studies. We discuss two different core configurations of ELSY reactor; one loaded with the reference – mixed oxide fuel (MOX), whereas the second one with an advanced fuel – uranium- -plutonium nitride. Both fuels consist of reactor grade plutonium, depleted uranium and additionally, a fraction of minor actinides (MA). The fuel burn-up and the time evolution of the reactor characteristics has been assessed using a Monte Carlo burn-up code (MCB). One of the important findings concerns the importance of power profile evolution with burn-up as a limiting factor of the refuelling interval.

Opis:
Based on mathematical modelling and numerical simulations, a control strategy for a Molten Carbonate Fuel Cell Hybrid System (MCFC-HS) is presented. Adequate maps of performances with three independent parameters are shown. The independent parameters are as follows: stack current, fuel mass flow and compressor outlet pressure. Those parameters can be controlled by external load, fuel valve and turbine-compressor shaft speed, respectively. The control system is purposed to meet many constraints: e.g. stack temperature, steam-to-carbon ratio, compressor surge limitation, etc. The aim is to achieve maximum efficiency of power generated within these constraints. Governing equations of MCFC-HS modelling are given. An operational line of the MCFC-GT system is presented which fulfils several constraints (temperature difference, cell temperature, etc.) The system is able to achieve efficiency of more than 62% even in part-load operation.

Opis:
This paper has been written based on the author’s doctoral dissertation “Structural and transportation properties of strontium and titanate composites with ion conductive oxides”, prepared under the supervision of Prof. Dr. Hab. Eng. Bogusław Kusz at the Department of Solid State Physics of Gdańsk University of Technology. It reports the idea of the thesis and conclusions from the study. Niobium doped strontium titanate (Sr(Ti,Nb)O3) composites with selected ion conductive oxides (yttrium oxide-stabilized zirconium oxide YSZ and cerium oxide CeO2) were developed for the dissertation and their properties examined.. It was shown that Sr(Ti,Nb)O3-YSZ composite as the anode in an oxide fuel cell leads to its improved performance compared to a cell with a singlephase Sr(Ti,Nb)O3 anode. Microscopic observation confirmed that Sr(Ti,Nb)O3-YSZ composite as the functional layer between a Sr(Ti,Nb)O3 anode and YSZ electrolyte mitigates the problem of the composite anode’s delamination from the electrolyte surface. It was also shown that an appropriate modification of the Sr(Ti,Nb)O3-YSZ composite anode surface structure by infusing the process of hydrogen’s electrochemical oxidation with a catalyst (e.g. with nickel) can lead to further improvement of the fuel cell performance.
Artykuł napisano na podstawie rozprawy doktorskiej autorki pt. „Właściwości strukturalne i transportowe kompozytów tytanianu strontu z tlenkami przewodzącymi jonowo”, przygotowaną pod nadzorem prof. dr. hab. inż. Bogusława Kusza w Katedrze Fizyki Ciała Stałego Politechniki Gdańskiej. Prezentuje on ideę pracy doktorskiej oraz wnioski wynikające z przeprowadzonych badań. W pracy doktorskiej wytworzono i zbadano właściwości kompozytów tytanianu strontu domieszkowanego niobem (Sr(Ti,Nb)O3) z wybranymi tlenkami przewodzącymi jonowo (tlenek cyrkonu stabilizowany tlenkiem itru – YSZ, tlenek ceru – CeO2). Wykazano, że zastosowanie kompozytu Sr(Ti,Nb)O3-YSZ jako anody prowadzi do poprawy parametrów pracy tlenkowego ogniwa paliwowego w stosunku do ogniwa z anodą 1-fazową Sr(Ti,Nb)O3. Obserwacje mikroskopowe potwierdziły, że zastosowanie kompozytu Sr(Ti,Nb)O3-YSZ jako warstwy funkcjonalnej między anodą Sr(Ti,Nb)O3 i elektrolitem YSZ ogranicza problem delaminacji anody kompozytowej z powierzchni elektrolitu. Wykazano również, że odpowiednia modyfikacja struktury powierzchniowej anody kompozytowej Sr(Ti,Nb)O3-YSZ poprzez nasączanie katalizatorami procesu elektrochemicznego utleniania wodoru (np. niklem) może prowadzić do dalszej poprawy parametrów pracy ogniwa paliwowego.

Opis:
There is a real need to use various efficient energy supply systems that are not aggressive towards the global environment. Hydrogen has been seen in different research papers presented in the literature as an essential fuel to generate energy in various energy storage systems. As it is well-known, it is possible to generate renewable electricity using electrolysis. The hydrogen produced can be sold as fuel for various systems, most notably its use in solid oxide fuel cells and a host of modern applications today. Current low-temperature fuel cells are ideal for hydrogen operation, but are not suitable for hydrogen mixtures. In this article, a mathematical analysis was carried out to generate electrical energy in a fuel cell, fed with synthesis gas from the residual biomass gasification process; the primary interest was the generation of electrical energy, solid oxide fuel cell (SOFC), which operate at the temperature of the gas at the outlet of the gasifier were analyzed. The practical efficiency obtained and the theoretical results of the SOFC operation were shown.

Celem badań było stworzenie miarodajnego i szybkiego modelu takiego reaktora. Do obliczeń równowagi reakcji chemicznych zastosowano toolbox Cantera w środowisku MATLAB. Przeprowadzone symulacje wyznaczyły opty-malną koncentrację powietrza i paliwa doprowadzanego do reaktora. Odpowiednio dobrane parametry pozwoliły na maksymalizację wytwarzanego wodoru, który wykorzystywany jest do napędzania ogniwa paliwowego.
CPOX reactors allow the usage of currently available fuels (natural gas, diesel, dodecane) to power solid oxide fuel cells. The aim of this research was to develop a reliable and fast model of such reactor. MATLAB’s Cantera toolbox was used for the chemical equilibrium calculations. The simulations set the optimum concentration of air and fuel supplied to the reactor. Properly selected parameters maximized the hydrogen yield used to power the fuel cell.

Opis:
The CFD modelling of heat transfer in a microtubular Solid Oxide Fuel Cell (mSOFC) stack has been presented. Stack performance predictions were based on a 16 anode-supported microtubular SOFCs sub-stack, which is a component of the overall stack containing 64 fuel cells. Both radiative and convective heat transfer were taken into account in the modelling. The heat flux value corresponded to the cell voltage of 0.7 [V]. Two different cases of the inlet air velocity of 2.0 and 8.5 [ms–1] were considered. It was found that radiation accounted for about 20–30 [%] of the total heat flux from the active tube surface, which means that the convective heat transfer predominated over the radiative one.

Opis:
The aim of the work was to develop a mathematical model for computing the steady-state voltage – current characteristics of a planar Solid Oxide Fuel Cell and to determine the performance of a new SOFC design. The design involves cross-flow bipolar plates. Each of the bipolar plates has an air channel system on one side and a fuel channel system on the other side. The proposed model was developed using the ANSYS-Fluent commercial Computational Fluid Dynamics (CFD) software supported by additional Fuel Cell module. The results confirm that the model can well simulate the diagonal current path. The effects of temperature and gas flow through the channels and a Membrane Electrode Assembly (MEA) structure were taken into account. It was shown that a significant increase of the MEA temperature at high current density can lead to hot spots formation and hence electrode damage.

Opis:
Based on mathematical modeling and numerical simulations, applicativity of various biofuels on high temperature fuel cell performance are presented. Governing equations of high temperature fuel cell modeling are given. Adequate simulators of both solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC) have been done and described. Performance of these fuel cells with different biofuels is shown. Some characteristics are given and described. Advantages and disadvantages of various biofuels from the system performance point of view are pointed out. An analysis of various biofuels as potential fuels for SOFC and MCFC is presented. The results are compared with both methane and hydrogen as the reference fuels. The biofuels are characterized by both lower efficiency and lower fuel utilization factors compared with methane. The presented results are based on a 0D mathematical model in the design point calculation. The governing equations of the model are also presented. Technical and financial analysis of high temperature fuel cells (SOFC and MCFC) are shown. High temperature fuel cells can be fed by biofuels like: biogas, bioethanol, and biomethanol. Operational costs and possible incomes of those installation types were estimated and analyzed. A comparison against classic power generation units is shown. A basic indicator net present value (NPV) for projects was estimated and commented.
