摘要 |
Sulfonic acid group-containing polyvinyl alcohol having crosslinked structures, which is obtained by heat treating a mixed solution of polyvinyl alcohol, a sulfonating agent and a crosslinking agent, a composite polymer membrane excellent in proton conductivity and methanol barrier property, which is obtained by applying the mixed solution to a water-absorptive or hydrophilic polymer membrane, followed by sulfonation and crosslinking, and an electrode for a fuel cell excellent in catalytic activity, which comprises sulfonic acid group-containing polyvinyl alcohol having crosslinked structures and fine catalyst particles carried on porous particles. |
