Opis:
W ramach projektu Lider finansowanego ze środków Narodowego Centrum Badań i Rozwoju zostało opracowane nowoczesne stanowisko do badania zarówno ogniw paliwowych jak i elektrolizerów. Zostało ono umieszczone w budynku Lubelskiego Parku Naukowo-Technologicznego, gdzie znajdują się doskonałe warunki do prowadzenia badań naukowych tego typu jak i komercjalizacji uzyskanych wyników. Zbudowane stanowisko badawcze jest typu uniwersalnego, przystosowane do badania membranowych ogniw paliwowych i elektrolizerów niskotemperaturowych (LTPEM) oraz wysokotemperaturowych (HTPEM). Jest to możliwe dzięki uniwersalnej badawczej jednostce sterującej zbudowanej na bazie modułu CompactRIO firmy National Instruments. Uzupełnieniem stanowiska są nowoczesne zasilacze oraz programowalne obciążenie prądowe. W przypadku ogniw/elektrolizerów HTPEM są one umieszczane w obudowie termicznej pozwalającej na pracę w temperaturach do 200 ⁰C. Prezentowane stanowisko zawiera całą niezbędną infrastrukturę dostarczania wodoru jak i system wykrywania nieszczelności. W artykule zostanie wykazane, że obecne badania ogniw paliwowych/elektrolizerów muszą być wspomagane innowacyjnymi technologiami komputerowymi.
Within the Project Lider funded by the National Research and Development Centre the modern test stand for both, fuel cells and electrolysers has been designed. It has been placed at the Lublin Science and Technology Park joint stock co., where there are excellent conditions for conducting this type of research as well as for commercialization of the results. Built test stand is the universal stand, adapted for the study of Proton Exchange Membrane fuel cells and electrolysers as well as Low Temperature (LTPEM) as High Temperature (HTPEM). It is possible due to universal laboratory control unit based on CompactRIO module of National Instruments. Completion for the stand are modern power suppliers and programmable current load. In case of HTPEM fuel cells/electrolysers they are placed in thermal casing allowing them to operate at temperatures up to 200°C. Presented stand includes all the necessary infrastructure of hydrogen supply and leak detection system. In the article it is shown that the current fuel cell/electrolysers research must be supported by innovative computer technologies.

Opis:
Renewable energy application is gaining a wide acceptance by end users; however, considering the fact that renewable energy is intermittent, variable and cannot be predicted, the need of storage systems is becoming a necessity at both micro and macro levels. Fuel cell technology is one of the most promising storage systems due to the fact that hydrogen has high energy density. This paper presents a design of stand-alone PV-PEMFC hybrid system for a small house under Amman climate. The simulation results show that the optimal size of PV array, fuel cell (PEMFC), inverter, electrolyzer (ELE) and H2 Tank capacity were 10 kW, 1 kW, 5 kW, 6 kW, and 5 kg respectively. Hydrogen proved itself as a low carbon energy source, which is environmental friendly and characterized with high energy content per unit mass. Due to fuel cells technology, hydrogen can be used for inter-season storage.

Opis:
The green energy sources are the utmost needs of today’s world where the reserves of fossil fuel are depleting day by day. The Distributed Generation (DG) has become integral part of power system at commercial level. The most efficient among all DGs and Renewable Energy Sources (RES) is the Fuel Cell (FC) power generation. The fuel cell invariably converts chemical energy directly into electricity. The Fuel cells have normally 60 to 70% efficiency at working conditions. The polarization curve of fuel cell plays important role in improving its efficiency. This research presents the mathematical and Simulink modeling 6 kW, 45 Vdc of Proton Exchange Membrane (PEM) fuel cell. The input thermodynamic parameters of fuel cell are varied and their effects on the output electrical variable are observed. The DC/DC boost converter is used to step up the voltage of fuel cell to 100 Vdc at commercial usable level. A new mathematical equation is presented to improve the efficiency of fuel. The mathematical results are then varied through Simulink results.

Test Without Active Gases
Opis:
High-Temperature Proton-Exchange Membrane Fuel Cells (HT-PEMFCs) are a candidate for electrical energy supply devices in more and more applications. Most notably in the aeronautic industry. Before any use, an HT-PEMFC is preheated and after that supplied with its active gases. Only at this state, the diagnostics can be performed. A method of testing not requiring a complete start-up would be beneficial for many reasons. This article describes an extended version of the charging and discharging diagnostic method of HT-PEMFCs with no active gases. This extended approach is named “Test Without Active Gases” (TWAG). This paper presents original research on the influence of nitrogen temperature and pressure on the HT-PEMFC response to charging and discharging. A lumped-element model of an HT-PEMFC is also presented. A numerical result of using this model to recreate an experimentally obtained curve is also presented.

Opis:
The aim of this paper was to demonstrate the feasibility of using a Computational Fluid Dynamics tool for the design of a novel Proton Exchange Membrane Fuel Cell and to investigate the performance of serpentine micro-channel flow fields. A three-dimensional steady state model consisting of momentum, heat, species and charge conservation equations in combination with electrochemical equations has been developed. The design of the PEMFC involved electrolyte membrane, anode and cathode catalyst layers, anode and cathode gas diffusion layers, two collectors and serpentine micro-channels of air and fuel. The distributions of mass fraction, temperature, pressure drop and gas flows through the PEMFC were studied. The current density was predicted in a wide scope of voltage. The current density – voltage curve and power characteristic of the analysed PEMFC design were obtained. A validation study showed that the developed model was able to assess the PEMFC performance.

Opis:
In the present study, a novel PVA–g–PMA hybrid membrane was developed for application in direct methanol fuel cell (DMFC). Maleic anhydride (MA) was grafted on polyvinyl alcohol (PVA) both ionically and chemically using potassium persulfate (KPS), for the first time. The PVA–g–PMA thus synthesized was then blended with 3–Amino–4–[3–(triethylammonium sulfonato)phenyl amino]phenylene hydrochloride. The prepared membranes were characterized by FT–IR, TGA. 0.0104 S/cm of proton conductivity was found for the membrane. The ion exchange capacity was found to be 2.175 meq/g and the water uptake capacity as 14.9%. The single-chamber fuel cell power density was higher (34.72 mW/cm2) and current density (62.11 mA/cm2) when compared to Nafion 117 membrane.
