| 摘要 |
A polymer electrolyte membrane includes a poly(benzoxazole) polymer doped with at least one acid. The polymer electrolyte membrane is manufactured by impregnating poly(benzoxazole) with an acid and has better ionic conductivity at high temperatures and better mechanical properties than a conventional poly(benzoxazole) polymer electrolyte membrane. In addition, the polymer electrolyte membrane has equivalent thermal stability to a conventional polymer electrolyte membrane.
