Abstract: A chemically regenerable redox fuel cell is disclosed. This fuel cell is one in which the oxidant is oxygen and the fuel is hydrogen. A catholyte solution is used. The catholyte solution is one which is reoxidized from a reduced state to an oxidized state by direct exposure of the catholyte solution to oxygen. An anolyte solution is also used. This anolyte solution is one which is reduced from an oxidized state to a reduced state by direct exposure of the catholyte solution to hydrogen. Structure is provided for containing in separate containers the catholyte solution and the anolyte solution, and for providing oxygen to the catholyte solution and hydrogen to the anolyte solution. A suitable cationic exchange membrane is housed in a housing and provided with volumes on opposite sides of the membrane for the catholyte solution and anolyte solution so that the necessary exchanges may take place to form the redox cell.
