Abstract
To provide a proton conductive material which has high proton conductivity even under no humidification and does not elute into water. A proton conductive material comprising a proton-source-polymer and a proton-channel-polymer, wherein at least one selected from the group consisting of the proton-source-polymer and the proton-channel-polymer is a polymer containing an aromatic ring, and wherein at least a part of the polymer containing the aromatic ring has a stacked structure formed by π-π interactions, and a proton conductive material comprising a proton-source-crosslinked-polymer, wherein the proton-source-crosslinked-polymer is a polymer having a main skeleton which contains a proton source group and an aromatic ring, and a crosslinked structure which contains a proton channel, and wherein at least a part of the proton-source-crosslinked-polymer has a stacked structure formed by π-π interactions.
