Classification: CPC H  Y | IPC H

Claim 0:
1. A planar type solid oxide fuel cell, comprising:
a unit cell which includes:
a fuel electrode including at least one fuel through hole having a first surface and at least one air through hole having a second surface;
an electrolyte layer located above the fuel electrode;
an air electrode located above the electrolyte layer; and
an insulating layer on a surface of the fuel electrode, the first surface of the at least one fuel through hole, and the second surface of the at least one air through hole,
wherein in the unit cell, the fuel electrode serves as a support,
wherein the electrolyte layer and the fuel electrode have a same size,
wherein the fuel electrode has a width extending from a first edge to a second edge,
wherein a width of the electrolyte layer is equal to the width of the fuel electrode so that the electrolyte layer does not extend beyond the first edge and the second edge of the fuel electrode,
wherein a size of the air electrode is smaller than the size of the fuel electrode, and
wherein the insulating coating layer and the electrolyte layer are formed by a same composition.
