<P>PROBLEM TO BE SOLVED: To provide a method and device for manufacturing a membrane electrode assembly capable of manufacturing a high quality electrode in high productivity. <P>SOLUTION: An adhesive layer 9 is formed on the surface of an electrolyte membrane 8, and the electrolyte membrane 8 is bonded to the lower surface of an upper electrode plate 1 so that the adhesive layer 9 faces a lower electrode plate 2. While vibrating a sieve 3 with a vibrating device 4, an electric field is generated between the upper electrode plate 1 and the lower electrode plate 2 with power sources 5, 6, an electrode material 7 on the lower electrode plate 2 is charged by the electric field, and moves toward the upper electrode plate 1 by the force from the electric field. At this point, even if the electrode material 7 is aggregated, it is dispersed by passing through the vibrating sieve 3, and uniformly bonded to the adhesive layer 9 of the electrolyte membrane 8 bonded to the lower surface of the upper electrode plate 1. By drying the adhesive layer 9, the electrode material 7 is fixed to the surface of the electrolyte membrane 8, and the membrane electrode assembly is manufactured. <P>COPYRIGHT: (C)2008,JPO&INPIT |
