Abstract
A bi-polar plate is provided for a fuel cell stack. The bi-polar plate has improved surface wettability. The bi-polar plate includes a body including at least approximately ninety percent by weight of a metal and defining at least one flow channel. At least about 0.05 percent and up to 100 percent by weight of silicon is disposed on a surface of the at least one flow channel to form a high energy surface to form a high energy surface for the bi-polar plate. This can be achieved by adding from 0.5 to 10 weight % silicon to the steel. The percent of silicon is pre-determined based on a desired wettability of the high energy surface of the at least one flow channel.
