The bipolar plate is one of the most important functional components in the polymer electrolyte-membrane fuel cell
The bipolar plate is one of the most important functional components in the polymer electrolyte-membrane fuel cell. Due to the large number of recurring units it contains, the plate is a major cost factor in the overall system
