Abstract
A proton conducting hydrocarbon-based polymer has acid groups on side chains attached to the main chain, where the acid groups are between 7 and 12 atoms away from the main chain. Another polymer includes a semi-fluorinated aromatic hydrocarbon main chain and side chains that include at least one —CF2— group and an acid group. Another polymer includes an aromatic hydrocarbon main chain and side chains that include at least one —CH2-CF2— group and an acid group. Another aromatic polymer includes acid groups attached to both the main chain and the side chains where less than about 65 weight percent of the acid groups are attached to the side chains. Another aromatic polymer includes side chains attached to the main chain that include at least one aryl ring, and acid groups attached to both the main chain and to the aryl groups. Another polymer includes an aliphatic hydrocarbon main chain, side chains that include at least one deactivating aryl ring, and acid groups attached to the deactivating aryl rings. Another aliphatic polymer has side chains that include —CF2— groups and an acid group. A fuel cell component includes a proton conducting polymer, a water insoluble inorganic material, and a heteropolyacid immobilized on the inorganic material.
