Abstract: An electrochemical cell is provided with first and second electrodes (50), and a solid polymer electrolyte disposed therebetween. The electrodes may either be of the same or different material and may be fabricated from ruthenium, iridium, cobalt, tungsten, vanadium, iron, molybdenum, hafnium, nickel, silver, zinc, and combinations thereof. The solid polymer electrolyte is in intimate contact with both the anode and cathode, and is made from a polymeric support structure having dispersed therein an electrolyte active species. The polymeric support structure is preferably a multi-layered support structure which includes a first polymeric layer (30), having first and second major surfaces (32, 34). Disposed on at least one, and preferably both surfaces is a layer of a different, second polymeric material (36, 38). The second polymeric material is preferably more formable than the first polymer layer so that it can easily fill pores (40, 42, 44, 46, 48) in the adjacent electrodes (50).
