Unit cell for solid oxide electrolyte type fuel cell and related manufacturing method

A cell unit for a solid electrolyte type fuel cell, comprising:

• an air electrode;
• a fuel electrode;
• a solid electrolyte sandwiched between the air electrode and the fuel electrode;
• and
• joining means for joining to at least one of the air electrode and the fuel electrode,
• wherein the joining means allows oxidizing gas, to be supplied to the air electrode, and fuel gas, to be supplied to the fuel electrode, to flow therethrough while allowing a cell power output to be collected from reacting areas provided by the sandwiched body composed of the air electrode, the fuel electrode and the solid electrolyte.

A method of manufacturing a cell unit for a solid electrolyte type fuel cell, the method comprising:

• forming a first layer, that corresponds to one of an air electrode and a fuel electrode, on a first porous metallic base body
• forming a second layer, composed of a solid electrolyte, on the first layer;
• forming a third layer, that corresponds to the other one of the fuel electrode and the air electrode, on the second layer;
• and
• joining a second porous metallic base body onto the third layer.
