Experimental runs were conducted on direct ammonia fuel cells. Effects of temperature, composition, as well as run effect and block effect were investigated extensively through a statistical study program. The block effect was due to the employment of two separate sets of cells--thus reflecting possible differences in cell preparation. The data was subjected to a detailed analysis of variance testing all primary and interaction effects. Measurement of single electrode potentials was made by means of a new type of a nickel-nickel oxide reference electrode. The development of this reference electrode is essential to all present and future kinetic studies on systems of this type. Experimental approaches related to problems in sealing cells and to electrode flooding are discussed. Data on performance of complete laboratory direct ammonia-oxygen fuel cells are presented and discussed. Author
