    • PROBLEM TO BE SOLVED: To enlarge backward water diffusion effect from cathode side to anode side by positively forming water content gradient in an electrolyte membrane in a fuel cell 1 that has a membrane electrode assembly 2 equipped with a reinforced electrolyte membrane 10A, in order to suppress drying of the anode side.
      SOLUTION: Two pieces of stretched porous membranes 12a, 12b having different porosity are embedded as reinforcing membranes in an electrolyte resin 11 to form the reinforced electrolyte membrane 10A. By using that reinforced electrolyte membrane 10A, the membrane electrode assembly 2 is composed in which the reinforcing membrane 12b side having larger porosity is arranged to become the cathode side, and pinched by separators 20, 30 to compose the fuel cell 1. In the case one sheet of reinforcing membrane is embedded, the reinforcing membrane is displaced toward the anode side, and embedded into the electrolyte resin.

    • PROBLEM TO BE SOLVED: To provide a proton conductor showing good proton conductance over a wide temperature range.
      SOLUTION: A polymer with an acidic group having acidic groups such as a sulfonic acid group, a phosphoric acid group, a phosphonic acid group, and a proton acceptor having a higher boiling point than 100°C under 1 atmospheric pressure and functioning as a medium transmitting proton dissociated from the acidic group are made to be held in a hole part of a porous body. Preferred examples of proton acceptors are a salt structure made of a cation and an anion originated from a basic organic compound, a basic organic compound, and a dissociation accelerating polymer accelerating dissociation of the proton. The polymer with the acidic group and the proton acceptor can be held in any order, or can be held simultaneously.
