Carbon based bipolar plate coatings for effective water management
Abstract:
A flow field plate for fuel cell applications includes a metal with a carbon layer disposed over at least a portion of the metal plate. The carbon layer is overcoated with a silicon oxide layer to form a silicon oxide/carbon bilayer. The silicon oxide/carbon bilayer may be activated to increase hydrophilicity. 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.
