Abstract:

Experimental work on the effects of high 113 F and low -80 F temperature storage effects upon standard RM cells was continued. A study of the effect of K2CO3 on the freezing point and on conductivity in the KOH-ZnO-H2O system is presented. Solubility data for K2CO3 in KOH-H2O, and in KOH-ZnO saturated with C form - H2O, were obtained at room temperature. The gassing tests for determining the effect of the ZnO content of electrolyte on amalgamated anodes were concluded. Storage tests on 1R structures, comparing various electrolytes, were concluded and the data was analyzed. The validity of the latest modification of the Haring Cell was established, and it is now being used to study electrode polarization in the RM system. Total polarization and anode passivity, as limiting factors in low-temperature cell design, are presented as functions of the ZnO content of electrolyte 30 KOH and electrode current density. Development of a unit cell for evaluation of cell structure is discussed, and theoretical and practical considerations of low-temperature cell design are presented.
