Abstract:
Bipolar plates useful for fuel cell applications include a plate body having a channel-defining surface that is at least partially coated with a hydrophilic layer. This hydrophilic layer comprises residues of a silane-coupling agent in a sufficient amount such portions of the first hydrophilic layer have a contact angle less than a predetermined value.
