    摘要: The present invention relates to a hydrogen storage alloy electrode composed of a hydrogen storage alloy having a CaCu5 region and a Ce2Ni7 region in the crystal structure and satisfies the relational formula: p:q=1:(4+a), where p is the sum of the mole fraction of an element occupying the Ca site of the CaCu5 region and the mole fraction of an element occupying the Ce site of the Ce2Ni7 region, q is the sum of the mole fraction of an element occupying the Cu site of the CaCu5 region and the mole fraction of an element occupying the Ni site of the Ce2Ni7 region, and −0.2≦a≦0.4. Accordingly, although the hydrogen storage alloy electrode contains a little or no Co, it is possible to obtain an electrode having little deterioration due to pulverization of the alloy and a high capacity.

    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.
