Production of layer system used for thin layer electrolyte in high temperature fuel cells comprises mixing anode material powder and solvent, spraying mixture onto substrate, drying, applying electrolyte layer and sintering

摘要

Production of a layer system consisting of a porous substrate, a porous anode functional layer and an electrolyte layer comprises mixing anode material powder and a solvent to form a sprayable mixture, spraying the mixture onto the substrate and drying, applying an electrolyte layer on the dry anode functional layer, and sintering. Preferred Features: The sprayable mixture has a solids content of at least 50 g/l. The applied anode material powder mixture is dried under normal pressure. Sintering is carried out without previous intermediate calcination.
