Abstract:
Two types of fuel cells were investigated, a cy lindrical electrode cell and a parallel plate electrode cell. A Vacuum Tube Voltmeter VTVM and load circuit were employed for preliminary studies of cell performance. Graphite electrodes were used in 30 KOH electrolyte and were exam ined by optical and electron microscopy and by spectrographic analysis before and after use. Individual electrode performance was studied with a precision load interruption circuit and electrometer preamplifier. A modified A.C. Kelvin bridge was used to provide information on ohmic polarization. Graphite electrodes were impreg nated with platinum and silver for hydrogen and oxygspectively. At operating temperatures of 25 to 45 C open-circuit potentials of about -1.0 volt for the anode and 0.16 volt for the cathode vs mercury-mercuric oxide were obtained. Current densities of 110-20 ma sq cm were observed at 0.95 volt. Author
