    摘要： A flow field plate for a fuel cell that includes an outer layer of a metal oxide or other material that makes the plate hydrophilic. The particular metal oxide and the thickness of the metal oxide layer are selected so that hydrofluoric acid generated by the fuel cell continuously etches away the layer at a predetermined rate so that a surface of the layer is free of contaminants over the entire life of the fuel cell. If the fuel cell does not employ a perfluorosulfonic acid membrane, then a separate hydrofluoric acid source can be provided that injects a low level solution of hydrofluoric acid into one or both of the reactant gas streams.

    摘要： A polymer composite bipolar plate for an electrochemical cell is formed with a hydrophilic surface. The thermosetting binder resin for the matrix of the composite preferably comprises aromatic groups or moieties and chemically resistant crosslinking bonds. After a mixture of binder resin precursors and conductive powder has been molded into a plate and thermally set, water-interactive chemical groups (i.e. ionic groups) are chemically attached to aromatic groups at the surface(s) of the plate to make the surface stably hydrophilic. For example, the surface of a styrene/divinyl benzene copolymer binder resin is sulfonated to make the surface hydrophilic.

    摘要： The present invention is directed to a fuel cell dielectric coolant and evaporative cooling process using same. The coolant comprises an emulsion that defines a polar internal phase and a hydrocarbon external phase. The polar internal phase comprises an azeotropic mixture that includes one or more polar compounds selected from water, alcohol, or combinations thereof. The fuel cell is configured to react fuel with oxygen to generate an electric current and at least one reaction product, and comprises an electrochemical catalytic reaction cell configured to include a fuel flowpath, an oxygen flowpath, and a coolant flowpath fluidly decoupled from the fuel and oxygen flowpaths, and which defines a coolant isolation manifold including the fluid dielectric coolant described above. The method of cooling a fuel cell comprises, inter alia, evaporating the polar internal phase of the fluid dielectric coolant emulsion in the coolant isolation manifold.
