Abstract
An object of the present invention is to provide a method for producing a membrane electrode assembly with excellent electrode transfer ability to electrolyte membrane. Disclosed is a method for producing a membrane electrode assembly, the assembly comprising an electrolyte membrane and an electrode which are attached to each other, the method comprising: a hot pressing step in which an electrolyte membrane and an electrode, the electrode comprising an electroconductive material and an electrolyte resin and being formed on a flexible substrate, are hot pressed to produce a laminate in which the electrolyte membrane, the electrode and the flexible substrate are laminated in this order, and a bending step in which the laminate is bent so that the flexible substrate side becomes concave, thereby removing the flexible substrate from the electrode.
