HIGH POLYMER ELECTROLYTE FUEL CELL

摘要

A high polymer electrolyte fuel cell comprising, laminated one upon another, a single cell, a collector plate, an insulating plate and end plates, the single cell being provided with a high polymer electrolytic membrane, a cathode and an anode having catalyst reaction layers and sandwiching the high polymer electrolytic membrane therebetween, a separator having a means for supplying a hydrogen-containing fuel gas to the anode and a separator having a means for supplying an oxydizing agent gas to the cathode, wherein a total heat exchanger for transferring heat and moisture simultaneously from an exhausted gas to the fuel gas and the oxydizing agent gas is built in on the inner sides of the end plates provided at the opposite ends of the fuel cell or between the insulating plate and the collector plate or the end plates, thereby making it possible to efficiently utilize after-use cooling water and to provide the high polymer electrolyte fuel cell having a compact internal total heat exchanger.
