Abstract: A solid oxide reactor provided with an electrode structure comprising a first electrode, a second electrode (6; 26), a first gas chamber (V1 ), a second gas chamber and an ion-conductive medium (8), wherein an ion-conductive medium is located between the first electrode (2) and the second electrode, wherein furthermore, the first electrode borders on the first gas chamber, and the second electrode borders on the second gas chamber. The first electrode comprises a first layer of a conductive oxide material, the conductive oxide material being composed of at least one electron-conducting oxide material provided with a defective structure and one ion-conductive oxide material provided with a defective structure. The second electrode comprises a first layer of a conductive oxide material, the conductive oxide material being composed of at least one electron-conductive oxide material provided with a defective structure and one ion-conductive oxide material provided with a defective structure.

Abstract: Electrochemical cell on the basis of electrode-supported thin electrolyte includes an anodic support (1) consisting of a nickel/zirconia material and an electrolyte layer (3) disposed that includes zirconia thereon and a cathode layer (6) which is in turn disposed thereon. To improve the quality of the cell and to increase the output it is proposed to arrange an auxiliary or intermediate layer (2) between the electrolyte layer and the anodic support. This auxiliary layer consists of nickel and zirconia particles which are substantially smaller than the particles of the support. Then an electrolyte layer (10) and, on the other side of the anodic support, a current collector layer are applied. None of these layers are sintered. Only after an assembly obtained in this manner has been obtained is a sintering treatment carried out.
