Performance studies were conducted extensively on direct ammonia fuel cells. Two new types of catalysts were studied and compared with platinum black. Gasketing problems and a new cell structure are discussed. Further improvements in techniques involved in making a complete material balance are described. Results of studies of formation of traces of nitrates and nitrites by chemical side reaction are discussed. Kinetics of the anodic oxidation of ammonia were analyzed theoretically and experimentally investigated in a special apparatus to determine the nature of the controlling step. Results indicate that oxidation of the intermediate metal-amine adsorbed species is rate controlling. Theoretical and practical considerations of the water balance and transport problems are discussed. Author
