US Patent No: 8338047

Solid oxide fuel cell

---

Abstract

---

The present invention is a solid oxide fuel cell configuration which equalizes gas volume distributed into each power generation cell to stabilize fuel cell output and improve the output efficiency. In the present invention, a flat plate laminating type solid oxide fuel cell has a reactant gas supply manifold extending through a fuel cell stack in the laminating direction, for supplying reactant gas to each of power generation cells through gas passages of separators which are communicated with the manifold. The manifold and the passages of the separators are in communication with each other through a gas-flow throttle mechanisms.
