Provided are an electrode for a fuel cell and a membrane electrode assembly that can control elution of catalyst particles and sufficiently extract the function of a catalyst added during operation of the fuel cell at a high current density. The electrode for a fuel cell contains an electrocatalyst formed by catalyst particles being supported on an electrically conductive carrier and an electrode material that contains a first ion conductor having anionic conductivity and a second ion conductor having cationic conductivity covering the electrocatalyst. The first ion conductor is disposed so as to cover the catalyst particles, and the second ion conductor is disposed so as to cover the first ion conductor and the exposed parts of the electrically conductive carrier. The membrane electrode assembly uses the electrode for a fuel cell in at least one of an anode and a cathode. |
