ABSTRACT:
In an apparatus A in which electrode powder10is allowed to adhere via the electrostatic force to an electrolyte membrane that serves as a substrate2so as to form a catalyst layer, a screen5is held in a state of non-contact with the substrate2,and a voltage is applied therebetween. The electrode powder10is allowed to adhere to an elastic feed roller7,and the feed roller7is allowed to rotate in contact with the screen5by pressure. The electrode powder10is dispersed toward the substrate2so as to stably adhere thereto via both the electrostatic force and the extruding force of the elastic body.Variation of thickness and collapse of the outline are extremely reduced on the catalyst layer to be transferred and formed on the substrate (electrolyte membrane) via the electrostatic force using a conventionally used mesh-like screen so as to obtain a membrane electrode assembly with a high product manufacturing accuracy.
