The method includes the steps of (a) providing an ionized arc nozzle comprising two consumable electrode and a working gas flow to form an ionized arc between the two electrodes, wherein the consumable electrodes provide the precursor catalyst material vaporizable therefrom by the ionized arc; (b) operating the arc nozzle to heat and at least partially vaporize the precursor catalyst material for providing a stream of nanometer-sized vapor clusters of the precursor catalyst material into a chamber in which the membrane or the electrode substrate has been placed; and (c) introducing a stream of a carrier gas into the chamber to impinge upon the stream of precursor vapor clusters to produce depositable nano clusters which are carried by the carrier gas to deposit onto a first side of the membrane or the electrode substrate for forming the nano-structured catalyst coating. Such a catalyst-coated membrane or electrode can be incorporated as a part of a fuel cell.

    摘要: This invention provides a highly electrically conductive sheet molding compound (SMC) composition and a fuel cell flow field plate or bipolar plate made from such a composition. The composition comprises a top sheet, a bottom sheet, and a resin mixture sandwiched between the top sheet and the bottom sheet. At least one of the top sheet and bottom sheet comprises a flexible graphite sheet, which has a substantially planar outer surface having formed therein a fluid flow channel. Further, the resin mixture comprises a thermoset resin and a conductive filler present in a sufficient quantity to render the flow field plate electrically conductive enough to be a current collector (preferably with a conductivity no less than 100 S/cm). Preferably, both the top and bottom surfaces are flexible graphite sheets, each having a substantially planar outer surface having therein a fluid flow channel formed by embossing. These two flexible graphite sheets are well-bonded by the middle resin mixture layer to form a highly conductive bipolar plate, which is particularly useful for proton exchange membrane fuel cell applications.
