ELECTROLYTE CONTAINING OXOCARBON MOLECULE AND USE THEREOF

摘要

The present invention provides, as an electrolyte which is useful as a material for a proton conductive membrane in a solid polymer fuel cell utilizing a gas fuel such as hydrogen gas or a liquid fuel such as methanol or dimethyl ether and which has higher proton conductivity than the conventional electrolytes do, an electrolyte characterized by containing an oxocarbon molecule, wherein the oxocarbon molecule has a difference in heat of formation ”E defined as:
”E = E 2 -E 1 (kcal/mol) satisfying the range of: ”E<-70 (kcal/mol),
wherein E 1 (kcal/mol) is a heat of formation in the state where a hydrogen ion is non-dissociated, and E 2 (kcal/mol) is a heat of formation in the state where a hydrogen having the lowest dissociation energy in the molecule ion is dissociated, both being calculated in regard to the stabilized molecular structure in accordance with a molecular orbital method.
