PROBLEM TO BE SOLVED: To impart a sufficient hydrogen ion conductivity and a sufficient mechanical characteristic by using fluorine-including pluralistic segmented polymer having plural number of fluorine included polymer chain segment as the electrode material, and including at least one kind of sulfonic acid type functional group having the ion conductive function. SOLUTION: Fluorine cont. segment including a fluorine cont. polymer chain segment including the sulfonic acid type functional group capable of having ion conductivity, and fluorine cont. segment including a fluorine cont. polymer chain segment capable of improving the mechanical characteristic is used so as to form the solid polymer electrode material suitable for fuel cell. As a sulfonic acid type functional group, SO3 M [M is hydrogen atom, alkali metal (rare earth group) salt, ammonia, or ammonium cation obtained by adding proton to primary to tertiary amine], and desirably, SO3 H, SO2 Cl, and SO2 F is used. As the equivalent number of florine cont. pluratistic segmented polymer, 400-1600 is desirable. |
