Abstract
An electrochemical cell is provided with first and second electrodes, and a solid polymer electrolyte disposed therebetween. The electrodes may either be of the same or different materials and may be fabricated from ruthenium, iridium, cobalt, tungsten, vanadium, iron, molybdenum, halfnium, nickel, silver, zinc, and combinations thereof. The solid polymer electrolyte is in intimate contact with both the anode and the cathode, and is made from a polymeric support structure having dispersed therein an electrolyte active species. The polymer support structure is preferably a multi-layered support structure in which at least a first layer is fabricated of a polybenzimidazole, and at least a second layer is fabricated of, for example, poly vinyl alcohol.
