Abstract
A method for preparing a fuel cell membrane electrode assembly, where the membrane electrode assembly includes a solid polymer electrolyte membrane and a first electrode and a second electrode provided on both sides of the solid polymer electrolyte membrane. The first electrode and the second electrode each include an electrode catalyst layer and a gas diffusion layer. The method includes forming the first electrode and the second electrode on both sides of the solid polymer electrolyte membrane, providing a preformed resin frame member around the solid polymer electrolyte membrane, overlapping an outer marginal portion of the first electrode and an inner marginal portion of the resin frame member with each other and applying heat and pressure to the overlapped portions of the first electrode and the resin frame member to join the resin frame member around the solid polymer electrolyte membrane.
