Abstract:
A flow field plate for fuel cell applications includes a metal with a non-crystalline carbon layer disposed over at least a portion of the metal plate. The non-crystalline carbon layer includes an activated surface which is hydrophilic. Moreover, the flow field plate is included in a fuel cell with a minimal increase in contact resistance. Methods for forming the flow field plates are also provided.
