A production method for a fuel cell membrane-electrode assembly which may include the steps of preparing a catalyst ink that contains a metal catalyst nanoparticle of 0.3 nm to 100 nm in primary particle diameter which is not supported on a support, an electrolyte resin, and a water-based solvent and forming a non-supported-catalyst containing catalyst layer by using the catalyst ink, as a catalyst layer that is included in at least one of a fuel electrode side and an oxidant electrode side in the fuel cell membrane-electrode assembly that has a fuel electrode at one surface side of an electrolyte membrane, and an oxidant electrode at another surface side of the electrolyte membrane. |
