ABSTRACT:
An electrochemical cell is fabricated by providing two symmetric electrodes and a solid polymer electrolyte disposed therebetween. The symmetric electrodes, anode and cathode, are made from materials such as ruthenium, iridium, cobalt, zinc, bismuth, cadmium, silver, and oxides thereof. The solid polymer electrolyte is in intimate contact with both the anode and cathode, and is made from a polymeric support structure such as polyvinylalcohol, having dispersed therein a proton conducting electrolyte active species.
