| 摘要 |
A membrane electrode assembly according to the invention includes a solid polymer electrolyte membrane and an electrode joined to each of two sides of the solid polymer electrolyte membrane. The solid polymer electrolyte membrane is such that some or all of the protons included in the entire solid polymer electrolyte membrane, a band region, or a non-power generating region are ion exchanged with one or more cations selected from among complex cations, class four alkylammonium cations, and high valence cations. In addition or alternatively, the solid polymer electrolyte membrane includes an organo-metalloxane polymer obtained by impregnating the entire solid polymer electrolyte membrane, the non-power generating region, or the band region with an organo-metalloxane monomer that includes an ammonium cation or a class four ammonium cation at its terminus and then hydrolyzing and polycondensing the organo-metalloxane monomer. |
