Document Type and Number:

WIPO Patent Application WO/2008/132875

Kind Code:

A1

Abstract:

Durability of a solid polymer fuel cell is improved by suppressing deterioration of a polymer electrolyte membrane of the solid polymer fuel cell without deteriorating power generation performance. Disclosed is a method for producing a polymer electrolyte membrane for a solid polymer fuel cell, wherein a polymer electrolyte membrane, in which a transition element or a rare earth element is uniformly dispersed, is formed by preparing a solution or dispersion of an alkoxide of a transition element or rare earth element having a catalytic power of decomposing a peroxide. This method for producing a polymer electrolyte membrane for a solid polymer fuel cell is characterized by the following feature (1): when the polymer electrolyte membrane, in which a transition element or a rare earth element is uniformly dispersed, is formed from a mixed solution which is obtained by preparing a solution of a polymer electrolyte and then uniformly mixing the solution with the solution or dispersion of an alkoxide, the alkoxide is condensed by hydrolysis, or alternatively by the following feature (2): the polymer electrolyte membrane, in which a transition element or a rare earth element is uniformly dispersed, is formed by preparing a polymer electrolyte membrane for a solid polymer fuel cell, then uniformly impregnating the polymer electrolyte membrane with the solution or dispersion of an alkoxide, and then condensing the alkoxide by hydrolysis.
