<P>PROBLEM TO BE SOLVED: To provide a hydrogen permeable membrane which is composed of a Pd membrane, a hydrogen permeable base material using V or a V alloy and an intermediate layer containing other elements of the group V, and can suppress the degradation of hydrogen permeability with time by oxidation, and to provide a fuel cell which uses the hydrogen permeable membrane and is improved the problem that the hydrogen permeability is degraded with time. <P>SOLUTION: The hydrogen permeable membraneis composed of the hydrogen permeable base material using V or a V alloy, hydrogen permeable Pd membrane containing Pd, and the intermediate layer provided between the hydrogen permeable base material and Pd membrane. The intermediate layer contains elements of the group V other than V, and has a dense structure. The fuel cell uses the hydrogen permeable membrane. <P>COPYRIGHT: (C)2007,JPO&INPIT |
