HYDROGEN-OXYGEN ELECTRODE STUDY
Abstract
Porous nickel (Clevite Corporation no. 3 Porous Nickel) electrolyte fuel cells were operated with an asbestos electrolyte holder impregnated with both free 30% KOH and gelled 15% and 20% KOH. Indications were that gelled KOH had less mobility than the free electrolyte and would not wet or drown electrodes as quickly as free electrolyte unless mechanical pressure was applied to force the gel into an electrode. Better contact was obtained between the electrode and the electrolyte holder when KOH gel was used. Higher current densities and less polarization were experienced at 60-70 C than at room temperature. A gel of 20% KOH produced better results than one of 15% KOH. High open circuit potentials were obtained with gelled electrolyte. The major problems were dehydration of the KOH saturated electrolyte holder and the inability of the cell to support heavy loads.
