Method for the production of polymer membrane-electrode-assemblies |
摘要 |
Membrane electrode array (MEA) for polymer electrolyte fuel cell with operating temperature up to 250[deg]C has membrane of basic polymer(s), sandwiched between 2 flat gas distribution electrodes that are charged with dopant and act as dopant reservoir for the membrane. After pressure and heat treatment, the doped membrane is proton-conducting and firmly bound to the electrodes. When doped, its conductivity is not less than 0.1 S/m at a temperature not less than 25[deg]C. Independent claims are also included for the following: (1) polymer membrane for an MEA, consisting of a polymer containing basic polymer(s), with a mechanical stability of over 110 N/mm 2> breaking strength and over 6% elongation at room temperature; (2) polymer electrolyte fuel cells for an operating temperature up to 250[deg]C with the specified MEA between bipolar plates. |
