  • Publication number: 20120244451
    Abstract: 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.

  • Publication number: 20110195363
    Abstract: A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and a second radiation-sensitive material adjacent the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has the first sensitivity and a second sensitivity different from the first sensitivity. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. The mask has a plurality of substantially radiation-transparent apertures. The first and second radiation-sensitive materials are then exposed to a plurality of radiation beams through the radiation-transparent apertures in the mask to form a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material. The first construct and the second construct cooperate to form the radiation-cured structure.
