EVALUATION OF THE PERFORMANCE OF POLYMER ELECTROLYTE MEMBRANE FUEL CELL (PEMFC) DESIGNED IN DIFFERENT SIZES

OpenAlex English

Fuel cells, which are the technology of the future, are the formation of electrical energy by the combination of hydrogen and oxygen as a result of a chemical reaction and the release of heat with H2O as waste. The fuel cell is a device that consists of an electrolyte and two electrodes during this coupling and converts chemical energy into electrical energy. Since electricity is produced without combustion, less pollution occurs. The part where the chemical reaction takes place in the Polymer Electrolyte Membrane (PEM) fuel cell consists of the membrane. In this study, the fuel consumption of different sizes (5-25-50 cm2) of fuel cells was investigated and the factors affecting the performance were determined experimentally. First of all, the PEM fuel cell was installed, and appropriate amounts of Hydrogen (H2) and Oxygen (O2) were sent to the fuel cell according to the characteristics of the established cell. During the study, the performances of different sizes of fuel cells were determined. The performance of fuel cells was evaluated according to their size and the amount of electrical energy they would produce was calculated. It was determined that the most efficient fuel cell is C60H60 with a size of 5 cm2, C60H46 with a size of 25 cm2 and C60H46 with a size of 50 cm2.
