Abstract
In this study, the temperature values of the fuels used in Polymer Electrolyte Membrane (PEM) fuel cell were determined and the optimum temperature ranges were obtained for these fuels. Pure hydrogen and oxygen were used in the anode and cathode portions. In this study, moisture was taken as 40%, hydrogen amount as 0.3 ml/min and oxygen amount as 0.5 ml / min. Line temperature values in the system were also tested between 40-80°C with a 5°C difference. In the experiments carried out at 40°C, when the volt value was taken as 0.442V and the current value was taken as 1.81A, the power value obtained in the system was found to be 0.804W. In the experiment, when the current value is 1.8A and the volt value is 0.535V at 75°C, the power value in the system is found to be 1.025W. The lowest W value was calculated as 0.804W at 40°C and the highest W value was calculated as 1.025W at 75°C. These calculations are presented in tables and graphs.
