摘要： An electrolytic cell for polymer electrolyte membrane electrolysis with a cathode half-cell and an anode half-cell is provided. The cathode half-cell and the anode half-cell being separated from one another by a polymer electrolyte membrane. The anodic half-cell has a gas diffusion layer. The gas diffusion layer is made from a fine-meshed metallic carrier material. An anodic catalyst layer with an anodic catalyst material is applied onto the polymer electrolyte membrane. The anodic catalyst layer is arranged adjacent to the gas diffusion layer, wherein a thin protective layer is applied in each case locally and selectively onto the fine-meshed carrier material in the area of the contact points between the gas diffusion layer and the adjoining anodic catalyst layer. The thin protective layer comprises iridium and/or iridium oxide so that the input of anodic catalyst material into the gas diffusion layer is inhibited.

摘要： The present invention relates to a manufacturing apparatus and method for customizing a H2/CO synthetic gas in a desired ratio by producing a synthetic gas in which H2 and CO are mixed through hydrolysis of both carbon dioxide and a nitrogen compound with low power. In a low-power electrochemical apparatus for producing a synthetic gas according to the present invention, by performing the reduction of the carbon dioxide at the cathode and the oxidation of the nitrogen compound at the anode at the same time, carbon dioxide conversion efficiency may be improved 30% or more compared to the conventional carbon dioxide conversion system, and a synthetic gas with a desired H2/CO ratio may be produced by controlling the H2/CO ratio of the produced synthetic gas, and by reducing a driving voltage, the corrosion problem of electrode materials may be inhibited and the durability of electrodes may be increased.
