A polymer composition, a polymer membrane containing the polymer composition, a method of manufacturing the same, and a fuel cell including the membrane |
| abstract |
The present invention (a1) at least one bis- (ortho-diamino) aromatic compound, (a2) polybenzimidazoles derived from at least one aromatic carboxylic acid or derivative thereof containing at least two acid groups and at least one hydroxyl group at the α-position of the carboxyl group; (b) orthophosphoric acid; And (c) polyphosphoric acid of formula (I) HO [P (O) (OH)] n H (I) Wherein the polyphosphoric acid of formula (I) is present in an amount of less than 2 mol% based on the sum of the moles of orthophosphoric acid (b) and the polyphosphoric acid (c), wherein n is an integer from 2 to 20, Orthophosphoric acid (b) is present in an amount of 1 to 75 moles per mole of benzimidazole group formed from (a1) and (a2); A polymer film containing the polymer composition; A preferred method of making the membrane; And A fuel cell comprising the membrane. |
