Abstract
A separator plate for a fuel cell is provided, including a substrate having a radiation-cured first flow field layer disposed thereon. A method for fabricating the separator plate is also provided. The method includes the steps of providing a substrate; applying a first radiation-sensitive material to the substrate; placing a first mask between a first radiation source and the first radiation-sensitive material, the first mask having a plurality of substantially radiation-transparent apertures; and exposing the first radiation-sensitive material to a plurality of first radiation beams to form a radiation-cured first flow field layer adjacent the substrate. A fuel cell having the separator plate is also provided.
