Abstract
A fuel cell using hydrogen sulfide as the fuel therefor, wherein the electrolytic cell is divided by a diaphragm into a positive electrode chamber and a negative electrode chamber, which fuel cell is operated by feeding a redox solution as the negative electrolyte to the negative electrode chamber, withdrawing from the electrolytic cell the redox solution which has been oxidized by reaction with the negative electrode, removing from the negative electrode chamber the sulfur produced by contact with hydrogen sulfide, and circulating to the negative electrode chamber only the redox solution which has been reduced by contact with hydrogen sulfide.
