Abstract

Disclosed is an apparatus for manufacturing a membrane electrode assembly, whereby a high-quality membrane electrode assembly, which has high adhesiveness between a solid polymer electrolyte membrane and a catalyst layer, and which does not have wrinkles, can be manufactured, while using a hot roll method. Also disclosed is a method for manufacturing the membrane electrode assembly. The apparatus for manufacturing a membrane electrode assembly is provided with: a preheating means, which preheats the solid polymer electrolyte membrane (10) and a catalyst layer supporting base material (12) that supports the catalyst layer on one surface of a transfer base material; a thermocompression bonding means, which forms a bonded member (14) by integrating the catalyst layer supporting base material (12) and the solid polymer electrolyte membrane (10) by applying heat and pressure; and a peeling means, which peels the transfer base material (16) from the bonded member (14).

Description

Technical field [0001] The present invention relates to a membrane electrode assembly (MEA: membrane-electrode assembly) manufacturing device and a membrane electrode assembly manufacturing method. Background technique [0002] Conventionally, as a method of manufacturing a membrane electrode assembly, a method has been proposed in which a catalyst layer supporting base material and a solid polymer electrolyte membrane are thermally pressure-bonded using a hot press or the like, and then the transfer base material is peeled off. [0003] For example, Patent Document 1 discloses a method using a heat press and a method using a heat roller (heat press roller). In the above method using a hot roller, a long solid polymer electrolyte membrane is brought into contact with a long catalyst layer supporting substrate disposed on both sides of the solid polymer electrolyte membrane carrying a catalyst layer, and is hot-pressed using a pair of hot-pressing rollers. By connecting, the...
