In an apparatus A in which electrode powder 10 is allowed to adhere via
the electrostatic force to an electrolyte membrane that serves as a
substrate 2 so as to form a catalyst layer, a screen 5 is held in a state
of non-contact with the substrate 2, and a voltage is applied
therebetween. The electrode powder 10 is allowed to adhere to an elastic
feed roller 7, and the feed roller 7 is allowed to rotate in contact with
the screen 5 by pressure. The electrode powder 10 is dispersed toward the
substrate 2 so 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.
