The flow field layer is one of disposed between the substrate and a diffusion medium layer, and disposed on the diffusion medium layer opposite the substrate. The flow field layer has at least one of a plurality of reactant flow channels and a plurality of coolant channels for the fuel cell. The fuel cell component may be assembled as part of a repeating unit for a fuel cell stack. A method for fabricating the fuel cell component and the associated repeating unit for the fuel cell is also provided. | 06-24-2010 |
20100159398 | LAYERED RADIATION-SENSITIVE MATERIALS WITH VARYING SENSITIVITY - A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and applying a second radiation-sensitive material to the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has 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. | 06-24-2010 |
