Abstract: A flow field plate for fuel cell applications includes an electrically conductive plate having a first surface defining a plurality of channels. An active area section and an inactive area section characterize the flow field channels. A hydrophobic layer is disposed over at least a portion of the inactive area section while a hydrophilic layer is disposed over at least a portion of the active area section.
