Abstract
In the method and apparatus for manufacturing a fuel cell electrode, electrode material is electrostatically held on a photosensitive drum with a prescribed pattern. The electrode material of the prescribed pattern is then transferred from the photosensitive drum onto an electrolyte membrane or a membrane of a diffusion layer. The transferred electrode material of the prescribed pattern is then fixed to the membrane. The electrode material may be electrostatically applied to the membrane a plurality of times in order to vary the electrode structure in the thickness direction.
