Abstract:

The experimental investigation has demonstrated that a static water electrolysis cell with a palladium-silver alloy hydrogen-diffusion cathode is technically feasible. The best result was obtained with an experimental cell constructed with a 14-inch-diameter palladium-silver alloy tube of 5-mil wall thickness 0.5-inch effective length, a matrix of Teflon threads and calcium hydroxide impregnated with an electrolyte of 50 weight percent sodium hydroxide, and a platinum screen anode. The cell was operated satisfactorily independently of gravity for a minimum of 24 continuous hours with 97-100 percent hydrogen transmission at 75 ampsq ft and 2.0 volts at 145C with water supplied as vapor 1 atmosphere partial pressure. Preliminary design estimates for a cell to supply breathing oxygen for 3 men 6 pounds O2 per day indicate a very small cell 25 pounds, 0.2 cu ft with low power consumption 760 watts. Author
