Membranes of polyazoles, processes for their preparation and fuel cells using such membranes |
| abstract |
The membranes according to the invention are obtainable from polyazoles having an inherent viscosity greater than 1.1 dl / g by a process comprising the steps: a) preparing a solution of the polyazoles in organic solvents, b) shaping the resulting solution into a membrane mold, c) heating the solution brought into the membrane mold to a temperature in the range of 50 to 90 ° C until the formation of a self-supporting membrane and d) annealing the membrane obtained from step c) at increasing temperatures in the range of 120 to 500 ° C until the content of solvents in the membrane is less than 5 wt .-%. The membranes according to the invention can be used in high-temperature fuel cells. They have an increased mechanical stability and possess after doping with phosphoric acid at the operating temperatures of the high-temperature fuel cells to 250 ° C a high long-term stability. |
