    摘要: A novel ion conductive material may be formed as a thin-film multilayered structure. The thin-film multilayered structure may be formed using multiple ion conductive sublayers of an electronic insulator and an ionic conductor. A nanometer-range thickness of the electronic insulator may be selected to provide desirable ion conductive properties that may be different from bulk material properties due to quantum size effects. The thin-film multilayered structure may behave in aggregate as an electronic insulator while behaving as an ion conductor at relatively low temperatures. The thin-film multilayered structure may be used as an electrolyte in a solid-oxide fuel cell (SOFC) for conduction of oxygen ions at relatively low temperatures, for example, less than about 600°C.

    摘要: Fuel cell electrodes comprising a minimal load of catalyst having maximum catalytic activity and a method of forming such fuel cell electrodes. The preferred method comprises vaporizing a catalyst, preferably platinum, in a vacuum to form a catalyst vapor. A catalytically effective amount of the catalyst vapor is deposited onto a carbon catalyst support on the fuel cell electrode. The electrode preferably is carbon cloth. The method reduces the amount of catalyst needed of a high performance fuel cell electrode to about 0.3 mg/cm or less, preferably to about 0.1 mg/cm . The electrocatalytic layer formed comprises unique, rod-like structures.

    摘要: The present application is directed to a fabrication method to reduce Pt loading in fuel cells through the use of thin film electrodes by increasing Pt utilization and the use of more active Pt alloys that can be easily and inexpensively fabricated by sputter deposition. Pt and Pt alloy thin films were sputter deposited onto carbon/Nafion® decals and subsequently hot pressed with the catalyst thin film towards the membrane. The results show improved mass performance and catalyst utilization with Pt thin films and increased mass activities can be achieved with PtCo (76:24 atomic ratio) and PtCr (80:20 atomic ratio) as compared to pure Pt. Mass activity improvements of 14 mV and 8 mV were observed for the PtCo and PtCr alloys with respect to a pure Pt film with similar mass loading under 300/350 kPa hydrogen/oxygen operation.

    摘要: The present invention relates to direct and reformate methanol fuel cells containing an anode comprising semiconductor layers. A semiconductor layer, preferably silicon or silicon carbide, is overlaid with a TiO 2 layer. An open metal over-layer, preferably platinum optionally applied over a layer of inert metal such as gold, is deposited on the TiO 2 layer, optionally in the form of a grid. It has been found that the active OH species generated in the presence and absence of light irradiation at the TiO 2 surface in this device eliminates the need for ruthenium to be present. Furthermore, studies have unexpectedly shown that an electric field applied via an electrode on the surface of the TiO 2 appears not to be required for the benefits to occur. This invention is thought to be particularly applicable to micro fuel cells.
