Abstract:

The following conclusions can be drawn after the investigation of hydrazine-air fuel cell systems Heat-treatment of the anode substrate, which was aimed at reducing unprefered oxides and at homogenizing the material, improved the electrode performance, primarily by reducing the NH3 content in the evolved gas Study of the catalytic oxidation of NH3 was completed. Some model reactors were successfully operated for several hundred hours Effects of various electrolyte parameters on the NH3 content in the evolved gas were studied. Significant effects were obtained by varying both the concentration of hydrazine and KOH, and the temperature of the electrolyte. The effect of CO3 contamination seemed insignificant A study of the common electrolyte problem was made. Two methods aimed at interrupting the electrolyte path seemed promising 3 X 3 inch full cell testing was carried out on some promising anodes. The sulfide treatment was optimized through full cell testing.
