SEPARATION MEMBRANE FOR FUEL CELL |
摘要 |
The present invention can provide an anion exchange type separation membrane used for direct liquid fuel type fuel cell, high in heat resistance, hard to deteriorate when using and capable of obtaining high battery output. A composite membrane used as the separation membrane for fuel cell can be obtained by using a porous film, composed of a hydrolysis resistant polyimide resin such as a polyimide resin having a fluorenylidene group in a main framework, as a substrate; optionally increasing water retention characteristics for example by applying a water-retentive resin to at least a part of a surface of the porous film; and then filling an anion-exchange resin such as a cross-linked hydrocarbon-based anion-exchange resin having a quaternary ammonium group as an anion exchange group into a void portion of the porous film. |
