Abstract
A solid oxide fuel cell includes a metal support which is formed from a porous metal substrate and which supports a power generation cell. The metal support includes a power generating area (GA) in which the power generation cell is disposed, and a buffer area (BA) which is formed on an outer side of the power generating area (GA) in an in-plane direction. A pore in the metal support in the buffer area (BA) is filled with a material with a thermal conductivity lower than that of a formation material of the metal support.

A solid oxide fuel cell comprising:
- a metal support which is formed from a porous metal substrate and which supports a power generation cell, wherein
- the metal support includes a power generating area in which the power generation cell is disposed, a buffer area which is formed on an outer side of the power generating area in an in-plane direction, and an outer peripheral area which is formed on an outer side of the buffer area in the in-plane direction, the metal support is located on the anode side of the power generation cell, a separator is located on the anode side of the power generation cell such that a void region is formed between the separator and the buffer area of the metal support,
- the power generation cell is formed as a stacked body of an anode electrode, a solid oxide electrolyte, and a cathode electrode, and
- a pore in the metal support in the buffer area is filled with a filler material with a thermal conductivity lower than that of a formation material of the metal support.
