    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 wt% 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.

    Abstract: A fuel cell component is made with a composite including a proton conducting polymer, a water insoluble proton conducting inorganic material, and a heteropolyacid immobilized by chemically bonding to the inorganic material. In another embodiment, the fuel cell component is made with a composite including a non- proton conducting polymer, a water insoluble inorganic material, and a heteropolyacid immobilized by chemically bonding to the inorganic material, the heteropolyacid causing the composite to show proton conductivity. In a further embodiment, the fuel cell component is made with a composite comprising a proton conducting polymer, a water insoluble proton conducting inorganic material, and a heteropolyacid immobilized by chemically bonding to the inorganic material, the composite having substantially identical structure of the unmodified heteropolyacid.

    Abstract: An ionically conductive polymer is a copolymer including first and second polymer segments. The first polymer segments have a hydrophobic character and a high oxygen permeability. The second polymer segments have a hydrophilic character and a low oxygen permeability. The copolymer has an ionic conductivity of at least about 1 x 10-5 S/cm at any point within a temperature range of from 30°C to 15O°C and a relative humidity range of from 20% to 100%. The ionically conductive polymer can be used in an electrochemical device such as a fuel cell, for example, used as a binder in an electrode or used to produce a membrane.
