Abstract

A cell includes a support substrate that is of a flat plate shape that includes a first principal surface and a second principal surface on an opposite side of the first principal surface and a columnar shape that includes a longitudinal direction and includes a gas flow path in an inside thereof, and a plurality of element parts that are arranged away from one another on the first principal surface and the second principal surface where at least a fuel electrode, a solid electrolyte film, and an air electrode are laminated thereon. The cell includes a first portion that is located on a side of the first principal surface with respect to the gas flow path and a second portion that is located on a side of the second principal surface with respect to the gas flow path. Structures of the first portion and the second portion are asymmetric.

Dependent claims

A cell, comprising:

a support substrate including:
a first surface;
a second surface opposite to the first surface;
and
a gas flow path between the first surface and the second surface;
a first element part laminated on the first surface, the first element part including at least a first fuel electrode, a first solid electrolyte film, and a first air electrode;
