Abstract

A method for manufacturing a membrane electrode and gas diffusion layer assembly includes: applying a catalyst ink including an ionomer to a second surface of an electrolyte membrane while conveying a first sheet in which a first surface of the electrolyte membrane is supported by a back sheet; drying the catalyst ink by blowing air vibrated with ultrasonic waves onto a surface of the catalyst ink to produce a second sheet in which a catalyst layer is provided on the second surface of the electrolyte membrane; forming a first roll by winding the second sheet; and producing a third sheet by stacking a gas diffusion layer on the catalyst layer and pressing them in a stacking direction as heating to join the catalyst layer and the gas diffusion layer while conveying the second sheet unwound from the first roll.
