Studies on the effect of humidifier temperature and hydrogen flow rate on the performance of the Proton Exchange Membrane Fuel Cell (PEMFC) using Pt/C and CoFe/N-C catalysts have been carried out. Membrane Electrode Assembly (MEA) is made of two electrodes, each coated with a Pt/C catalyst on the anode side and CoFe/N-C on the cathode side. The second MEA was made using a Pt/C catalyst both at …
