Opis:
In 1800 Alessandro Volta published the results of several years’ work on the phenomenon of electric shocks which he experienced from physical contact with the terminals of his newly developed battery. His work was prompted by Luigi Galvani’s explanation of involuntary muscle spasms in frog’s legs, which he induced and attributed to animal electricity. Volta’s paper opened the floodgates for research in the new field of electrochemistry which has resulted in today’s worldwide electric battery industry. This essay explains the sequence of natural events and their explanations which led to the publication of Volta’s paper, and gives an overview of the scientific research resulting from Volta’s work. This research includes attempts to improve batteries, and the development of ideas which led to a better understanding of matter and the way it interacts with energy. Practical details for the teaching of several important chemical concepts are listed in the appendix. The experiments are related to a reaction which has been known for many centuries - that between iron and copper sulphate solution.

Opis:
In recent years, regarding the influence of the production processes and vehicles on the environment, new technical solutions for reducing air pollutions have been studied and developed. One of the new constructions is fuel cell electric vehicle (FCEV). The production and running conditions of the vehicles are specific in different countries. Hence, a study of these conditions and fuel production process is needed. In this paper, a study of the FCEV efficiency, at different producing technologies of hydrogen (H2), is carried out. Life cycle assessment (LCA) method is used. A comparison, concerning fuel consumption and emissions as CO2 equivalent for the whole life cycle, is done for FCEV and conventional gasoline vehicle (GV). The influence of the energy mix and technology of production of hydrogen on spent energy and air pollution is analyzed. As the results show, in countries with CO2 emissions over 447 g per 1 kWh electricity, the technology of hydrogen production from natural gas is most effective. Now and in the near future, the ecological and financial advantages, connected to renovation of existing vehicle fleet with FCEV, are not absolutely verified.

Opis:
The publication analyses the possibility of separating hydrogen from coke oven gas for further use in the transport sector in the FCEV segment (fuel cell electric vehicles). The construction of the separation installation using the PSA (pressure swing adsorption) method guaranteeing high purity of hydrogen was assumed, according to the requirements of ISO 14678-2:2012 and SAE J-2719 standards. The PSA technology is widely used in industrial gas separation processes, however, due to the composition of coal gas, which apart from hydrogen and methane consists of impurities in the form of hydrocarbons, sulphur compounds, chlorine, etc., it needs to be adapted to the needs of separation of hydrogen from coke oven gas. The study shows the total possible hydrogen production potential and then, in agreement with the JSW Group’s Coking Plants, limits were set for hydrogen production in PSA technology at Przyjaźń, Jadwiga and Radlin Coking Plants, without the negative impact of the separation installation on technological processes associated with coke oven battery firing, operation of existing power units, gas compression systems and taking into account securing the needs of external customers for coke oven gas. Additionally, in order to determine the Polish market demand for high-purity hydrogen, an analysis was carried out which indicates that in 2030 the share of FCEVs will be 2%, so the demand for hydrogen in this segment would be negligible compared to the supply of hydrogen produced in a large-scale installation. Due to the need to build such a market and adapt the parameters of the installation to the variable parameters of coke oven gas, the pilot scale of the installation and the target location of the installation at the Przyjaźń Coking Plant were indicated as the most optimal.

Opis:
This study analysed the greenhouse gas (GHG) emissions of hydrogen fuel cell vehicles’(FCEVs’) life cycles. These included models running on hydrogen derived from coke oven gas (COG), which is a by-product of the coking process of coal and includes hydrogen, methane, and other gases. FCEVs and hydrogen have the potential to drive future mobility. Hydrogen can be separated from the COG in the process of pressure swing adsorption to obtain a purity of hydrogen that meets the requirements of a hydrogen FCEV. An environmental life cycle assessment (LCA) of FCEV powered by hydrogen produced from Polish COG was conducted. The direction of hydrogen production strategies in Poland was also presented. The analyses included the entire life cycle of FCEVs with the production of hydrogen from COG in a Polish coke plant. A comparative analysis of FCEVs and other alternative fuels was conducted, and the main determinants of GHG emissions of FCEV were given. Importantly, this is the first attempt at an environmental assessment of FCEVs in Poland.

Opis:
In the recent times, lot of research work carried out in the field of fuel cells explicitly divulges that it has the potential to be an ultimate power source in upcoming years. The fuel cell has more storing capacity, which enables to use in heavy power applications. In these applications, power conditioning is more vital to regulate the output voltage. Hence, we need a dc-dc converter to provide a constant regulated output voltage for such high-power system. Currently, many new converters were designed and implemented as per the requirement. This paper has made comparative study on several topologies of the quadratic high gain dc-dc converter and the applications where these topologies can be used when the fuel cell is given as a source. Also, we have compared various parameters of all the converters considered and generated the results with steady-state and dynamic study. In this article, we briefed the types of analysis carried on the dc-dc converter to study its performance. Moreover, various application of fuel cell is presented and discussed. This paper will be a handbook to the researchers who start to work on high gain dc-dc converter topologies with quadratic boost converter as a base. This article will also guide the engineers to concentrate on the fuel cell components where it needs to be explored for optimizing its operation.

This article presents the results of work related to the power supply system for 10kW electric, rental go-kart. The research took into account a few types of battery cells. For the case study, the best option was chosen taking into account the restrictions included in the multicriteria analysis for further application. Chosen BLDC motor and battery type were tested on test stands and simulated in MATLAB/Simulink. Simulation model allowed to compare the characteristics from test stands and simulation and next tune the model. Minimum capacity of the batteries had to allow for at least 20 minutes of drive. Chosen elements: electric motor, motor controller, battery cells, BMS allowed to build the first prototype. Tests in real conditions showed the difference between simulation and research system. We could notice what to improve to tune the simulation model and the kart power supply system.

Opis:
Major markets across the European Union (EU) are concentrated on rapid development of electromobility. This policy is demonstrated - among others - by recent sales of electric cars: within the past 3 quarters of 2018 - 24.7 thousand electric cars have been registered in Germany, 20.3 thousand in France, 15.3 thousand in the Netherlands and 31.4 thousand in Norway. Unfortunately, only 867 EVs have been registered in Hungary, 469 in the Czech Republic, 468 in Romania, 411 in Poland and 348 in Slovenia. Unit energy consumption of electric cars was often defined in NEDC cycle. In real conditions of road traffic, it may differ from values recorded in a drive cycle. The article presents results of a study on energy consumption of electric cars in Poland along RDE (Real Driving Emissions) testing route in terms of vehicle energy consumption per drive unit (km, 100 km). The use of fuel cells in cars may bring a change in the type of used vehicles in the long run. Both globally and in the EU wide-ranging actions are undertaken to implement fuel cell technology. Also, the infrastructure of hydrogen filling stations is developed. At present the most rapidly developing country in this area is Japan. The article addresses the issue of energy consumption per drive unit by cars equipped with fuel cells as both type of vehicles, i.e. EV and FCV use electric motors. The article also discusses infrastructure development in the EU and Poland, charging and fuelling of the said vehicles, respectively.
