Abstract: A proton conductor includes an anionic molecule and a cationic organic molecule. The anionic molecule is an anionic metal complex molecule. For example, the anionic metal complex molecule includes at least one chemical bond between a metal ion and an oxoacid ion. For example, the proton conductor can be used as an electrolyte membrane included in a fuel cell.

Abstract: A proton conductor includes a coordination polymer having stoichiometrically metal ions, oxoanions, and proton coordinating molecules capable of undergoing protonation or deprotonation. The coordination polymer including coordination entities that are repeatedly coordinated to bond the coordination entities with one another. Each coordination entity is either a first coordination entity or a second coordination entity. The first coordination entity is one metal ion of the metal ions coordinated with either at least one oxoanion of the oxoanions or at least one proton coordinating molecule of the proton coordinating molecules. The second coordination entity is the metal ion coordinated with each of at least one oxoanion of the oxoanions and at least one proton coordinating molecule of the proton coordinating molecules. At least a part of the proton conductor is non-crystalline. The proton conductor has high ion conductivity at high temperature.

Abstract: A fuel cell electrolyte includes: a porous member; and a proton conductive material supported by the porous member. The proton conductive material includes a metal ion, an oxoanion, and a proton coordination molecule. At least one of the oxoanion and the proton coordination molecule coordinates with the metal ion to provide a coordination polymer. A relative density is equal to or higher than 75%.

Abstract: A fuel cell electrode includes an intra-electrode proton conductor and a catalyst. The intra-electrode proton conductor contains a metal ion, an oxoanion, and a proton coordinating molecule, and at least one of an oxoanion and a proton coordinating molecule coordinates to the metal ion to form a coordination polymer. The intra-electrode proton conductor is disposed in contact with the catalyst. For example, the catalyst is covered with the intra-electrode proton conductor.
