摘要:
A flow field plate having a low resistance coating for fuel cell applications is described. In one embodiment, the flow field plate includes a metal plate having a first surface and a second surface, the first surface defining a plurality of channels for directing flow of a first gaseous composition; and an activated carbon coating disposed adjacent to at least a portion of the plate, the activated carbon coating having a surface resistance of less than about 20 mΩ·cm2, the surface resistance being stable. Fuel cells incorporating the flow field plates and methods of making the flow field plates are also described.
