20180342738 · 2018-11-29 ·

An electrolyte membrane with a backsheet is sent out from an electrolyte membrane unwinding roller, and is separated with its second side sucked on a suction roller by a first press roller. While the electrolyte membrane from which the backsheet has been separated is transported with the electrolyte membrane sucked and supported on the suction roller, an electrode ink is applied to a first side of the electrolyte membrane to form an electrode ink layer, which is dried by blowing hot air thereto to form a catalyst layer. Thereafter, in a state in which the outer surface of a second press roller disposed close to the suction roller is in contact with and supported on the first side of the electrolyte membrane, a support film is pressed against the second side of the electrolyte membrane by a third press roller and attached thereto to manufacture a catalyst-coated membrane.
