PROCESS FOR PRODUCING A MEMBRANE FOR THE OPERATION OF FUEL CELLS AND ELECTROLYZERS |
摘要 |
A membrane used in polymer electrolyte-fuel cells, containing sulfonated aromatic polyetherketone (sPEEK) of general formula (I), characterized in that the ion exchange equivalent (IEC) of said sulfonated polyetherketone is 1.35- 1.95 nmol (-SO3H)/g (polymer) and in that the membrane has a long-term stability of at least 1,000 hours at an operating voltage of 0.4-1.1V. |
