Abstract

The present invention provides a fuel cell that can secure an effective area of the fuel cell while suppressing a parasitic resistance of the fuel cell. In the fuel cell according to the present invention, a conductive substrate is disposed so as to contact a porous support layer at a location where a through-hole is not formed, and a structure allowing gas to flow in a direction orthogonal to an extending direction of the through-hole is formed at an interface between the conductive substrate and the porous support layer at the location (see FIG. 1).

Dependent claims

A fuel cell comprising:

a conductive substrate having a first through-hole;
a porous support layer disposed on the conductive substrate and having a second through-hole;
and
a fuel cell disposed on the porous support layer,
wherein
the fuel cell comprises:
a first electrode layer;
an electrolyte layer disposed on the first electrode layer;
and
a second electrode layer disposed on the electrolyte layer,
the conductive substrate is disposed so as to contact the porous support layer at a location of the conductive substrate where the first through-hole is not formed, and
a structure allowing gas to flow in a direction orthogonal to an extending direction the first through-hole is formed at an interface between the conductive substrate and the porous support layer at the location.
