摘要： A fuel cell includes a membrane electrode assembly comprised of a membrane sandwiched between anode and cathode catalyst structures. An anode separator plate and a cathode separator plate are arranged adjacent to the membrane electrode assembly opposite from one another. The anode and cathode separator plates include opposing sides in which one of the opposing sides of the anode and cathode respectively have fuel and oxidant flow fields in communication with the membrane. The anode separator plate is a structure having a first water permeability and is configured to permit passage of water between its opposing sides and with its flow field, and the cathode separator plate comprises a structure having a second water permeability less than the first water permeability of the anode separator plate. In one example, the anode is provided by a porous separator plate, and the cathode is provided by a non-porous, or solid, plate.

摘要： A method of processing a porous article includes distributing a blended material that includes an electrically conductive material and a binder into a cavity of a mold that is at a temperature below a curing temperature of the binder. The electrically conductive material is formed from particles of the electrically conductive material that have a size distribution such that 10 vol % of the particles are less than 12 micrometers in diameter, 50 vol % of the particles are less than 27 micrometers in diameter, and 90 vol % of the particles are less than 53 micrometers. The blended material is compressed within the cavity under a molding pressure, and the mold is heated to a curing temperature of the binder to form a molded article.
