Abstract

Solid polymer membrane fuel cell product water which forms on the oxidant side of the membrane is removed from the active area of the cells in a fuel cell power plant by being absorbed into and wicked away from the active area by a porous carbon body which contacts the membrane. The carbon body may be an oxidant reactant flow field plate. The pores in the carbon body are partially filled with metal oxide granules which impart increased wettability and water absorption capacity to the carbon body.
