摘要: The invention relates to a method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell. In a first step, the method preferably comprises the provision of a glass-ceramic substrate. A mesoporous catalyst layer is then preferably synthesized on the glass-ceramic substrate. In a next step, a polymer membrane is preferably pressed onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T1. This results in a sandwich structure. In a final process step, the sandwich structure is separated, the catalyst layer being separated from the glass-ceramic substrate and adhering to the polymer membrane.
In addition, the invention relates to a polymer membrane which has been produced by the process of the type mentioned at the outset, and to an electrolyser or a fuel cell having such a polymer membrane.-

摘要: Disclosed herein are doped perovskite oxides. The doped perovskite oxides may be used as a cathode material in an electrochemical cell to electrochemically generate ammonia from N2. The doped perovskite oxides may be combined with nitride compounds, for instance iron nitride, to further increase the efficiency of the ammonia production.

摘要: An abrupt interface electroreduction catalyst includes a porous gas diffusion layer and a catalyst layer providing a sharp reaction interface. The electroreduction catalyst can be used for converting CO2 into a target product such as ethylene. The porous gas diffusion layer can be hydrophobic and configured for contacting gas-phase CO2 while the catalyst layer is disposed on and covers a reaction interface side of the porous gas diffusion layer. The catalyst layer has another side contacting an electrolyte and can be hydrophilic, composed a metal such as Cu and is sufficiently thin to prevent diffusion limitations of the reactant in the electrolyte and enhance selectivity for the target product. The electroreduction catalyst can be made by vapor deposition methods and can be used for electrochemical production of ethylene in reaction system.
