    摘要: A fuel cell component includes a first fluid distribution layer, a second fluid distribution layer, a cap layer, a third fluid distribution layer, and a pair of fluid diffusion medium layers. The individual layers are polymeric, mechanically integrated, and formed from a radiation-sensitive material. The first fluid distribution layer, the second fluid distribution layer, the cap layer, the third fluid distribution layer, and the pair of fluid diffusion medium layers are coated with an electrically conductive material. A pair of the fuel cell components may be arranged in a stack with a membrane electrode assembly therebetween to form a fuel cell.
