PROCESS FOR PRODUCING POLYELECTROLYTE MEMBRANE, POLYELECTROLYTE MEMBRANE, MEMBRANE-ELECTRODE ASSEMBLY, AND FUEL CELL |
| 摘要 |
<p>This invention provides a process for producing a polyelectrolyte membrane, comprising a membrane forming step of forming a membrane from a polyelectrolyte solution containing a hydrocarbon block-type polyelectrolyte and a solvent to produce a solvent-containing block-type polyelectrolyte membrane and a heat treatment step of heating the solvent-containing block-type polyelectrolyte membrane to form a polyelectrolyte membrane. The process is characterized in that the temperature of the heat treatment is a temperature above the heat decomposition start temperature of the hydrocarbon block-type polyelectrolyte, and the residual amount of the solvent in the polyelectrolyte membrane after the heat treatment is brought to not less than 1% by weight.</p> |
