SOLID OXIDE FUEL CELL STACK

摘要

PURPOSE: A solid oxide fuel cell stack is provided to improve efficiency of fuel cells by sufficiently heating the fuel cell stack in advance. CONSTITUTION: A fuel cell stack(200) comprises: a first oxidant chamber(R3) with an oxidant supply pipe(212a); a second oxidant chamber(R6) which oxidizes and reduces an oxidant from an oxidant chamber; and oxidant paths which are connected to the first oxidant chamber and the second oxidant chamber, and transfers heat from the second oxidant chamber. The oxidant paths are installed only on both sides near the oxidant supply pipe.
