Disclosed are methods manufacturing a four-layer membrane electrode assembly integrated with an adhesive film. The methods include a step of preparing a three-layer membrane electrode assembly comprising a first electrode and a second electrode by attaching the first electrode to a first surface of an electrolyte membrane, attaching the second electrode to a second surface of the electrolyte membrane, and joining a first gas diffusion layer to the first electrode; and a step of attaching an adhesive film to the three-layer membrane electrode assembly by preparing the adhesive film by attaching an upper protective film to an upper surface of the adhesive film and a lower protective film to a lower surface of the adhesive film, removing the lower protective film, and attaching the adhesive film to an outer peripheral region of the membrane electrode assembly including the second electrode.
