Investigation of timely change of hydrogen consumption in fuel cell

Nowadays, renewable energy sources are inevitable due to the increasing need for energy, the diminishing of fossil fuels and the negative environmental impacts of fossil fuels used in energy production. The fuel cell consists of an electrolyte and two electrodes, which converts chemical energy into electrical energy and generates electricity through chemical reactions in the electrodes. Since electricity is produced without combustion, less pollution occurs. In this study, a 3x3cm fuel cell consisting of 8 cells was used. Polymer Electrolyte Mebrane Fuel Cell (PEMYP) as the fuel cell type is determined by the time and power produced by the hydrogen used massively. During the experiments, the humidity was 60%, the line temperature was 70°C and the cell temperature was fixed at 41°C. In this study, H2 and O2 values of the fuel cell were calculated separately by changing the power in the range of 0,1 - 1ml/min. A single cell H2 output of 0,2ml/min, O2 of 0,4ml/min of 1,065W power was obtained. In the light of the data, graphs were drawn by using the findings obtained from the equations and presented for interpretation and discussion.
