METHOD FOR MANUFACTURING POLYMER ELECTROLYTE MEMBRANE, AND FUEL CELL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a composite polymer electrolyte membrane of a basic polymer for a fuel cell and a strong acid having improved proton conductivity and mass productivity. <P>SOLUTION: A method for manufacturing a polymer electrolyte membrane 12 comprises the step of immersing a basic polymer such as polybenzimidazole in a strong acid of sufficient concentration for impregnating the basic polymer with 6 or more molecules of the strong acid per repeating unit of the polymer at temperatures of 30°C or higher for 5 hours or less. A fuel cell comprises the polymer electrolyte membrane. <P>COPYRIGHT: (C)2012,JPO&INPIT |
