Claim Text:
1. A method for fabricating a fuel cell component, the method comprising the steps of: providing an electrically conductive substrate having a first surface and a second surface, the first surface and the second surface disposed on opposite sides of the electrically conductive substrate; disposing a plurality of layers of radiation-sensitive material on the first surface and the second surface of the electrically conductive substrate; forming a first fluid distribution layer having a plurality of first channels and a plurality of second channels on the first surface of the electrically conductive substrate; forming a second fluid distribution layer on the second surface of the electrically conductive substrate; forming a cap layer on the first fluid distribution layer, the first channels of the first fluid distribution layer covered by the cap layer and the second channels of the first fluid distribution layer not covered by the cap layer; forming a third fluid distribution layer on the cap layer, the cap layer separating the first channels of the first fluid distribution layer from the third fluid distribution layer, the second channels of the first fluid distribution layer in fluid communication with the third fluid distribution layer; and forming a pair of diffusion medium layers including a first diffusion medium layer and a second diffusion medium layer, the first diffusion medium layer formed on the third fluid distribution layer, and the second diffusion medium layer formed on the second fluid distribution layer, wherein the first fluid distribution layer, the second fluid distribution layer, the cap layer, the third fluid distribution layer, and the pair of diffusion medium layers are formed by selectively exposing the plurality of layers of radiation-sensitive material to a plurality of radiation beams from at least one radiation source.
