摘要： A titanium sub-oxide/ruthenium oxide composite electrode and a preparation method and application thereof. Titanium-based titanium sub-oxide nanotubes is taken as a bottom layer, and titanium sub-oxide doped ruthenium oxide is taken as a surface composite active layer. A titanium substrate is anodized in a fluorine-containing ionic electrolyte, taken out, subjected to heating and roasting, cooled and then subjected to cathodic electrochemical reduction in polarizing liquid, so that a titanium-based titanium sub-oxide nanotube electrode is obtained; and then the titanium-based titanium sub-oxide nanotube electrode is taken as a cathode to be electrodeposited in a ruthenium trichloride electrolyte doped with titanium sub-oxide powder, taken out and then subjected to heating and roasting, so that the titanium sub-oxide/ruthenium oxide composite electrode is obtained.

摘要： The invention is directed to a barrier layer for corrosion protection in electrochemical devices, e.g. carbon based gas diffusion layers (GDLs) in electrochemical devices, comprising electrically conductive ceramic material and a non-ionomeric polymer binder. The electrically conductive ceramic material has an electrical conductivity of >0.1 S/cm, preferably >1 S/cm in air atmosphere (as detected by the powder method) and is selected from the group of precious metal and/or base metal containing oxides, carbides, nitrides, borides and mixtures and combinations thereof. Membrane-electrode assemblies (MEAs), catalyst-coated membranes (CCMs), gas diffusion electrodes (GDEs) and gas diffusion layers (GDLs) comprising the barrier layer of the invention show improved corrosion resistance, preferably against carbon corrosion; particularly in start-up/shut-down cycles and fuel starvation situations of PEM fuel cells.

摘要： Electrochemical device using thin micro-porous metal sheets. The porous metal sheet may have a thickness less than 200 μm, provides three-dimensional networked pore structures of pore sizes in the range of 2.0 nm to 5.0 μm, and is electrically conductive. The micro-porous metal sheet is used for positively and/or negatively-charged electrodes by providing large specific contact surface area of reactants/electron. Nano-sized catalyst or features can be added inside pores of the porous metal sheet of pore sizes at sub- and micrometer scale to enhance the reaction activity and capacity. Micro-porous ceramic materials may be coated on the porous metal sheet at a thickness of less than 40 μm to enhance the functionality of the porous metal sheet and may function as a membrane separator. The electrochemical device may be used for decomposing molecules and for synthesis of molecules such as synthesis of ammonia from water and nitrogen molecules.

摘要： The invention provides electro-catalyst compositions for an anode electrode of an acid mediated proton exchange membrane-based water electrolysis system. The compositions include a noble metal component selected from the group consisting of iridium oxide, ruthenium oxide, rhenium oxide and mixtures thereof, and a non-noble metal component selected from the group consisting of tantalum oxide, tin oxide, niobium oxide, titanium oxide, tungsten oxide, molybdenum oxide, yttrium oxide, scandium oxide, cooper oxide, zirconium oxide, nickel oxide and mixtures thereof. Further, the non-noble metal component can include a dopant. The dopant can be at least one element selected from Groups III, V, VI and VII of the Periodic Table. The compositions can be prepared using any solution based methods involving a surfactant approach or a sol gel approach. Further, the compositions are prepared using noble metal and non-noble metal precursors. Furthermore, a thin film containing the compositions can be deposited onto a substrate to form the anode electrode.
