To provide a new proton conducting hydrocarbon-based polymer.
The proton conducting hydrocarbon-based polymer includes a semi-fluorinated aromatic hydrocarbon main chain and side chains that include at least one -CF2- group and an acidic group. An aromatic polymer includes acidic groups attached to both the main chain and the side chains where less than about 65 wt.% of the acidic 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 acidic 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 deactivated aryl ring, and acid groups attached to the deactivated aryl rings. Another aliphatic polymer has side chains that include -CF2- groups and an acidic group. A fuel cell component includes a proton conducting polymer, a water insoluble inorganic material, and a heteropolyacid immobilized on the inorganic material.
