METHOD FOR PRODUCING A MEMBRANE USED TO OPERATE FUEL CELLS AND ELECTROLYZERS |
| 摘要 |
Membranes for use in polymer electrolyte fuel cells or electrolyzers comprise a sulfonated aromatic polyether ether ketone of the formula (I)wherein the ion exchange equivalent (I.E.C.) of the sulfonated polyether ether ketone is in the range from 1.35 to 1.95 mmol (-SO3H)/g (polymer) and the membrane has a long-term stability of at least 1000 hours at an operating voltage of from 0.4 to 1.1 V. |
