Cell plate structure for solid electrolyte fuel cell, solid electrolyte fuel cell and related manufacturing method

A method of manufacturing a cell plate structure for a solid oxide electrolyte type fuel cell, comprising:

• forming a lower electrode layer;
• forming an upper electrode layer, the upper electrode layer being provided in opposition to the lower electrode layer;
• forming a solid electrolyte layer, which is provided between the lower electrode layer and the upper electrode layer;
• allowing a substance to be contained in at least one of the lower electrode layer and the upper electrode layer;
• and
• executing a post-treatment by removing the substance, contained in the at least one of the lower electrode layer and the upper electrode layer during formation thereof, after the at least one of the lower electrode layer and the upper electrode layer has been formed, to make the at least one of the lower electrode layer and the upper electrode layer porous, the substance being removed from the at least one of the formed lower electrode layer and the formed upper electrode layer while leaving the at least one of the formed lower electrode layer and the formed upper electrode layer.
