Abstract
The present invention relates to a manufacturing method of an anode for a solid oxide fuel cell (SOFC), an anode, and a SOFC, in which an anode is formed by stacking sheets having a plurality of holes, and the holes are used as gas diffusion paths through which fuel gas can be facilely diffused, and some of the holes are filled with a reinforcement member or a current collecting member, thereby improving a cell strength and increasing a current collecting performance and thus an efficiency of the SOFC.
Claims23
A fabricating method of an anode (fuel electrode) for a solid oxide fuel cell (SOFC) having an electrolyte layer;
- and an anode and a cathode formed to be contacted with both surfaces of the electrolyte layer, comprising the steps of:
- a) preparing a plurality of sheets forming the anode;
- b) forming holes in each sheet;
- c) forming a first layer by providing a sheet, in which the holes H are not formed, at an uppermost side, and forming a second layer by stacking the plurality of sheets, in which the holes are formed at each sheet, at a lower side of the first layer so that the holes formed in the sheets are communicated with each other;
- and
- d) sintering the stacked sheets.
