Abstract
Provided is a fuel cell that is laminated via a separator to constitute a fuel cell stack. The fuel cell includes an anode layer, a solid electrolyte layer, and a cathode layer laminated in this order on a metal support on the separator. The metal support and the anode layer are made of a porous metal, and a reforming catalyst is formed inside at least one of the metal support and the anode layer. A thermal conduction inhibiting layer is formed between the metal support and the separator, the thermal conduction inhibiting layer being joined to the separator at least at a portion where the fuel cell and the separator are joined to each other and inhibiting thermal conduction from the separator to the metal support.

A fuel cell that is laminated via a separator to constitute a fuel cell stack, the fuel cell comprising:
- an anode layer, a solid electrolyte layer, and a cathode layer laminated in this order on a metal support on the separator, wherein
- the metal support and the anode layer are made of a porous metal, and a reforming catalyst is formed inside at least one of the metal support and the anode layer, and
- a thermal conduction inhibiting layer is formed between the metal support and the separator, the thermal conduction inhibiting layer being joined to the separator at least at a portion where the fuel cell and the separator are joined to each other and inhibiting thermal conduction from the separator to the metal support.
A method for manufacturing a fuel cell, the method comprising:
- laminating an anode layer made of a porous metal, a solid electrolyte layer, and a cathode layer in this order on a metal support made of a porous metal, then performing co-sintering with a thermal conduction inhibiting layer made of a porous metal from a lower surface side of the metal support, and integrating the anode layer, the solid electrolyte layer, the cathode layer, and the thermal conduction inhibiting layer to form a laminate;
- forming a reforming catalyst in at least one of the anode layer and the metal support;
- and
- joining a lower surface of the thermal conduction inhibiting layer in the laminate to a separator.
