This work is to gain the theoretical and practical information on solid electrolyte -- cerolyte -- hydrogen-oxygen fuel cells necessary to the construction of a power plant for space. A 50-watt cerolyte battery will be constructed and a 500-watt fuel-cell power plant will be designed. Research and development work is devoted to producing rugged, long-lived, efficient, electrodes and seals. The program as a whole is divided into four parts 1 electrode development 2 seal development and battery testing 3 design, construction, and testing of a 50-watt power system and 4 design and evaluation of a 500-watt cerolyte fuel-cell power system for space. During the first quarter work has been concentrated in the first two areas.
