A proton conductive composition, a membrane using the same, and a fuel cell are provided. A solution of a polymer compound having ion conductivity is added to a general formula (1). (Wherein n represents an integer of 0, 1, 2 or a positive value of 2 or more as an average value), a proton obtained by drying a solution obtained by adding a zirconium phosphate represented by A conductive composition, a proton conductive membrane comprising the composition, and a fuel cell using the proton conductive membrane. [Effect] The proton conductive membrane has high proton conductivity at high temperature (80 ° C or higher) and low relative humidity (relative humidity (RH) 60% or lower). Excellent power generation characteristics are exhibited even in an environment of humidity (relative humidity (RH) 60% or less). [Selection figure] None |
