A method for operating a fuel cell power plant. The fuel cell can include a reactant passage (22) with an upstream portion and a downstream portion for providing reactant to an electrode (16, 18), at least one liquid passage (24), and a plate (20) made from a porous material that is liquid permeable and conductive.
