    摘要: An electrolyte membrane-gasket assembly for a fuel cell, including a polymer electrolyte membrane and a gasket, made of a seal material, covering the peripheral portion of the electrolyte membrane, in which the electrolyte membrane has a sequence of a plurality of through-holes in the peripheral portion, and a portion of the gasket covering one surface of the electrolyte membrane and a portion covering the other surface are connected to each other through the through-holes of the electrolyte membrane. This assembly provides a polymer electrolyte fuel cell free from gas cross leakage caused by a detachment of the gasket from the polymer electrolyte membrane. It is preferable to further include catalyst layers carried on both surfaces of the polymer electrolyte membrane, respectively, and protective films covering, respectively, sections spanning from the peripheral portion of each of the catalyst layers to the peripheral portion of the polymer electrolyte membrane.

    摘要: When a polymeric electrolyte type fuel cell operating at about 60.degree. C. is used, heating with exhaust gas becomes difficult. Therefore, a polymeric electrolyte type fuel cell (PEM) is adopted as a fuel cell body, and a hydrogen storage vessel made of a metal containing hydrogen is connected to the PEM by a hydrogen supply piping via a humidifier for humidifying the electrolyte membrane of the PEM. The PEM and the hydrogen storage vessel are connected by a copper plate which is a conductor of heat. Heat generated in the PEM is transferred to the hydrogen storage vessel by this copper plate, and elevates the temperature and pressure in the vessel. By this, hydrogen is well supplied to the PEM.
