Abstract
A diffusion medium layer for a fuel cell, including an electrically conductive microtruss structure disposed between a pair of electrically conductive grids is provided. At least one of the microtruss structure and the grids is formed from a radiation-sensitive material. A fuel cell having the diffusion medium layer and a method for fabricating the diffusion medium layer is also provided.
