ELECTROLYTE CONTAINING OXOCARBON MOLECULE AND USE THEREOF

摘要

An electrolyte that is useful as a material for proton conductive membrane of a solid polymer fuel cell utilizing a gas fuel, such as hydrogen gas, or a liquid fuel, such as methanol or dimethyl ether, and that exhibits a proton conductivity higher than those of conventional electrolytes. There is provided an electrolyte characterized by containing oxocarbon molecules wherein when E₂ refers to a heat of formation (kcal/mol) exhibited in the state of dissociation of hydrogen ions with the lowest dissociation energy among the molecules while E₁ refers to a heat of formation (kcal/mol) exhibited in the state of non-dissociation of hydrogen ions, as calculated with respect to the state of stabilization of molecular structure by the use of molecular orbital method, the difference in heat of formation ?E defined by the formula: ?E = E₂ - E₁ (kcal/mol) satisfies the relationship: ?E < -70 (kcal/mol).
