Abstract
A method for fabricating a fuel cell component includes the steps of providing a mask having a plurality of radiation transparent apertures, a radiation-sensitive material having a sensitivity to the plurality of radiation beams, and a flow field layer. The radiation-sensitive material is disposed on the flow field layer. The radiation-sensitive material is then exposed to the plurality of radiation beams through the radiation transparent apertures in the mask to form a diffusion medium layer with a micro-truss structure.
