    摘要： The invention relates to a method for producing a ceramic cathode layer on an electrically conducting substrate, in which first a coating in the form of a suspension, comprising at least one suspending agent and at least one ceramic material, is applied to this electrically conducting substrate. This is followed by heating the coating in a reducing atmosphere such that the ceramic material is fully or partially reduced to a fusible reaction product. After that, the coating is heated in a reducing atmosphere to temperatures above the melting point of the reaction product, thereby forming a molten substance. This is followed by densifying or sintering of the coating in a reducing atmosphere at temperatures that lie 100°C above the melting temperature of the reaction product. A reoxidation of the densified or sintered coating subsequently takes place in an oxidizing atmosphere in a temperature range between 400 and 1200°C, wherein the reaction product is oxidized again and reacts again into the original composition of the ceramic material used.

    摘要： The invention relates to a method for producing a nanostructured electrode for an electrochemical cell. Active material is deposited onto an electrically conductive substrate by means of magnetron sputtering, a ceramic target comprising electrode material (active material) with an additional content of carbon is used, and the substrate is kept at temperatures between 400 °C and 1200 °C during the deposition. The invention additionally relates to a nanostructured electrode for an electrochemical cell, comprising a coating made of an active material on an electrically conductive substrate. The nanostructured active material has a porous structure which does not have a preferred direction perpendicular to the substrate surface. The active material of the electrode preferably has a fibrous structure, wherein the fibers have a diameter ranging from 10 to 500 nm, in particular from 10 to 200 nm, and the porosity lies between 20 and 90%. The nanostructured electrode can be produced in an advantageous manner using the aforementioned method.

    摘要： The rechargeable energy store according to the invention is based on a metal-air battery, in which a gas electrode is used and an ion- or proton-conducting membrane is used as the electrolyte. As a difference from the known metal-air batteries, in the case of the energy store according to the invention the active component is in the form of a liquid medium on the side of the electrolyte membrane that is opposite from the gas electrode. The liquid-medium/gas battery according to the invention has a container that holds a medium in liquid form as the active material at the operating temperature of the battery. The following are suitable inter alia as such a material: metals, semimetals, oxygen-containing compounds including simple or complex oxides, nitrogen-containing compounds, carbon-containing compounds, hydrogen-containing compounds, phosphorus-containing compounds, halogen-containing compounds, other chalcogen-containing compounds, silicon-containing compounds, germanium-containing compounds or boron compounds, in particular with one or more metals or semimetals (with respect to the entire list of the oxides up to the boron compounds), or mixtures thereof, as long as they are in a liquid form at operating temperatures.
