(JP11345620-A)   NOVELTY - A polymer electrolyte fuel cell is a laminate cell formed from a plurality of unit cells composed of a pair of electrodes with a catalyst layer, a polymer electrolyte film interposed between the electrodes, a separator having means for supplying hydrogen-containing gas to one of the electrodes, and a separator with means to provide oxidizing gas to the other electrode by stacking with sealant to at least a part of the peripheries of the electrodes.    USE - The fuel cells are particularly applicable as portable power supply in electric cars and domestic co-generator systems.    ADVANTAGE - Such polymer electrolyte fuel cells are operable at room temperature, with durability, reliability and productivity.
