    Operating Characteristics of Proton-Exchange-Membrane (PEM) Fuel Cells
    (European Journal of Scientific Research, 2008-04) Tamakloe, Reuben Y.; Singh, K.; Linkous, Clovis A.; 0000-0002-5563-5930
    The H2-O2 fuel cells in which solar hydrogen and oxygen supplied to the anode side and cathode side of the cell respectively were fabricated and the two sides of the cells were separated by a proton-exchange-membrane (PEM) which allowed the passage of hydrogen ions H+ but not the oxygen O2. The operating characteristics of two fuel cells, Al-C/Pt- PEM-C/Pt-Al and Al-C/Pt-PEM-C/Pt-Cu were plotted and internal resistance as well as the efficiency of these cells were computed and compared. It was found that Al-C/Pt-PEMC/ Pt-Cu cell did not clearly exhibit mass transport over-potential, while it was clearly observable for Al-C/Pt-PEM-C/Pt-Al cell.
