Hydrogen electrode made of palladium film modified with nanostructured palladium

摘要

The utility model relates to the field of electrochemistry, namely to the device of structural elements of hydrogen pumps and oxygen-hydrogen fuel cells, specifically to the device of hydrogen electrodes. The electrode includes a palladium membrane 1, made in the form of a foil, with a thickness of 1-30 microns. On both sides of membrane 1, a dispersed coating layer is applied in the form of stable nano-sized palladium crystallites in the form of five-petal colors 2. The palladium membrane 1, on the one hand, by spot welding is a point 3, is fixed on the surface of a porous metal base 4. The base 4 is metallic and electrically contacted with a metal gas distribution plate 5. In the volume and on the surface of the plate 5 from the side of the membrane 1, a system of gas distribution (purge) channels 6 is formed, ending in gas end fittings 7 with valves. Based on the electrode of the proposed device, it is possible to create oxygen-hydrogen fuel cells and hydrogen pumps, with a reduced content of precious palladium and with more stable electrical characteristics in time - specific power. 4 ill.
