Abstract
Disclosed herein is a solid oxide fuel cell including a unit cell, wherein the unit cell includes: a cylindrical internal electrode: an interconnector having a T-shaped cross section and stacked on an outer peripheral surface of the internal electrode in a length direction; an electrolyte stacked on the outer peripheral surface of the internal electrode except for the interconnector; and an external electrode stacked on an outer peripheral surface of the electrolyte except for wing parts of the interconnector. In addition, disclosed herein is a manufacturing method of a solid oxide fuel cell.
Claims16
A solid oxide fuel cell comprising a unit cell, wherein the unit cell includes:
- a cylindrical internal electrode:
- an interconnector having a T-shaped cross section and stacked on an outer peripheral surface of the internal electrode in a length direction;
- an electrolyte stacked on the outer peripheral surface of the internal electrode except for the interconnector;
- and
- an external electrode stacked on an outer peripheral surface of the electrolyte.
A manufacturing method of a solid oxide fuel cell, the manufacturing method comprising:
- providing a unit cell in which an internal electrode, an electrolyte, and an external electrode are sequentially stacked;
- exposing an outer peripheral surface of the electrolyte by removing a portion of the external electrode in a length direction of the unit cell;
- exposing an outer peripheral surface of the internal electrode by removing a portion of the exposed outer peripheral surface of the electrolyte;
- and
- stacking an interconnector on the outer peripheral surface of the internal electrode and the removed portion of the electrolyte.
