| 摘要 |
The present invention relates to proton exchange membranes for use in proton exchange membrane fuel cells, in particular in high temperature polymer electrolyte membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC), comprising sulfonated polybenzimidazole polymers; and to methods for the production of such proton exchange membranes. The invention further relates to novel sulfonated polybenzimidazole polymers and their use as a component of a proton exchange membrane in proton exchange membrane fuel cells. Moreover, the present invention relates to proton exchange membrane fuel cells, comprising such proton exchange membranes. |
