BASIC STUDIES ON FUEL CELL SYSTEMS

Abstract

The alkaline, aqueous N2H4, NH3 and CH2O anodes, and the intermediate NH3-O fuel cell system were evaluated. Preliminary results were obtained with alkaline O and air cathodes. The most feasible systems were the aqueous N2H4 and the aqueous NH3-O or air fuel cells. Evidence that NH4 is anodically oxidized through H as an intermediate in alkaline electrolyte was obtained. Reduction of the surface area of the N2H4 black Pt anode catalyst was investigated for possible optimization with respect to N2H4 decomposition rate and anode polarization. N2H4 anode gases were analyzed at closed and open circuits. N2H4 was consumed at the cathode in multiple-cell fuel cells. The molten caustic NH3 anode oxidized NH3 to nitrate and nitrite at 150 deg C. The black Pt CH2O anode had poor life in alkaline electrolyte.
