FLAT PLATE TYPE FUEL BATTERY

摘要

PROBLEM TO BE SOLVED: To equalize a fuel gas flow in a plane of a fuel electrode.SOLUTION: A flat plate type fuel battery comprises: a flat type fuel battery cell; and a flat plate type fuel electrode-side interconnector laminated on a plane on a fuel electrode side of the cell. The fuel electrode-side interconnector comprises: a fuel supply hole 9 formed in a central portion; a fuel recovery hole 10 formed in two outer circumferential places at positions 180° apart from each other; and a flow channel adjustment convex portion 14 shaped like a circular arc in a plan view and formed adjoining the fuel recovery hole 10 on a plane facing a fuel electrode of the cell at a position closer to the central portion than the fuel recovery hole 10. The length of the arc of the flow channel adjustment convex portion 14 is set in such a way that a flow channel length from the fuel supply hole 9 to the fuel recovery hole 10 for fuel gas flowing out in a direction toward the fuel recovery hole 10 and a flow channel length to the fuel recovery hole 10 for the fuel gas flowing out in a direction orthogonal to this flow-out direction of the fuel gas are substantially the same.
