PROBLEM TO BE SOLVED: To provide a high molecular electrolyte that has oxidation resistance which is equal to or more than that of a fluorine electrolyte, or practically sufficient and can be manufactured at low cost by forming it from a high molecular compound having a hydrocarbon part and introducing a functional group including phosphorus. SOLUTION: Because a functional group containing phosphorus such as a phosphonic acid group is introduced alone or simultaneously with another electrolyte group into a high molecular compound having a hydrocarbon part, the oxidation resistance of the high molecular compound having a hydrocarbon part is improved, and a solid high molecular electrolyte having high durability can be provided. In addition, because the high molecular compound having a hydrocarbon part is relatively less expensive, the high molecular electrolyte having oxidation resistance which is equal to or more than that of a fluorine electrolyte, or practically sufficient can be manufactured at low cost by introducing the functional group containing phosphorus in the range of 0.1-100 mol.% of the whole electrolyte group. If it is used, for instance, as an electrolyte film for a solid high molecular type fuel cell, the solid high molecular type fuel cell excellent in durability can be manufactured at low cost. |
