Method for manufacturing a solid oxide fuel cell element by layer-wise buildup and solid oxide fuel cell element

摘要

A method for manufacturing a solid oxide fuel cell element by layer-wise buildup wherein at least one section of the element is built up by carrying out a step that at least includes the following at least once: applying a layer section of a particulate ceramic material with predefined dimensions onto a base layer in a predefined area and heating the layer section by means of a heat source such that the particles of the ceramic material connect to one another within the predefined dimensions. The solid oxide fuel cell element manufactured with the method is realized in one piece, as well as highly compact, and has a low weight.

1. A method for manufacturing a solid oxide fuel cell element by layer-wise buildup, wherein at least one section of the solid oxide fuel cell element is built up by carrying out a step that at least comprises the following at least once:
applying a layer section of a particulate ceramic material with predefined dimensions onto a base layer in a predefined area; and heating the layer section by a heat source such that the particles of the ceramic material connect to one another within the predefined dimensions, wherein two, three, four or more layer section groups are strung together at least sectionally in a radial extension and at least sectionally in an axial extension, each layer section group including at least one anode of a first composition, at least one electrolyte, at least one cathode of a second composition and at least one air duct or channel structure.
