A catalyst which is made by reaction of nickel and cobalt salts with sodium dithionite has been developed in order to obtain active electrodes for water electrolysis. In acidic solutions of pH between 2.7 and 4.0 the dithionite decomposes to sulfur, hydrogen sulfide, and sulfite. This reaction was used by us to activate electrodes in the presence of nickel and cobalt salts. The electrodes obtained were used in alkaline water electrolysis, both as cathodes and as anodes. The tests were performed in 6 N KOH at a temperature of 70/sup 0/C. The potentials were measured relative to a mercury-mercuric oxide reference electrode.
