INVESTIGATION OF HYDRAZINE-AIR FUEL CELL SYSTEMS
Abstract
Fuel efficiency of the hydrazine-air fuel cell system can be significantly increased by selecting a proper electrode substrate. It must be a poor hydrogen electrode material, according to the mixed potential concept. Both the anode potential and the fuel efficiency were improved by applying a minute amount of catalyst poisons such as S= and Se=. The anode potential was increased by increasing the concentration of KOH and N2H4 in the electrolyte. The anode potential was not affected by C1- up to 200 mg/1, but it was lowered by CO=3 and Fe++ in the electrolyte. NH3 in the exhaust gas from the anode was satisfactorily decomposed by Pt catalyst. In addition to fuel cell grade asbestos separator, which has given the best results, some nonasbestos separators such as ThO2 membrane and alkaline battery separator also showed the promising results for the N2H4 - air system.
