Abstract:
A bipolar plate for fuel cells includes a flow plate having a first surface for the introduction of hydrogen fuel gas and water vapor and a second surface for the introduction of an oxygen containing gas, wherein at least a portion of the first and/or second surface comprises a nanostructured carbon material (NCM) coating deposited thereon, said coating having a thickness of 1 nm to 5 μm.
