| 摘要 |
A membrane for use in a proton exchange membrane fuel cell at a temperature in excess of 100°C comprises a membrane formed from a polymer capable of being doped with one or more acid groups or which is pre-complexed with one or more acid groups, and a porous particulate material is disclosed. The polymer may be a polyazole. The porous particulate material may be 20-80 % by weight of the polymer and may be a stable, non-electrically conducting inorganic material. |
