Patent ID: 7867665

Claim:
A fuel cell stack comprising: a plurality of cells which generate electrical power using a liquid fuel and an oxidant, the plurality of cells being vertically stacked; conductive end plates between which the plurality of cells is sandwiched; a collector and an insulating body between one of the end plate and the plurality of cells, and; an inlet portion of a fuel supply manifold which distributes the liquid fuel to each of the cells, and an outlet portion of a fuel discharge manifold which discharges discharge fuel discharged from each of the cells, the inlet portion and the outlet portion being electrically connected to each other, wherein the inlet portion of the fuel supply manifold and the outlet portion of the fuel discharge manifold are provided in one of the conductive end plate above the vertically stacked plurality of cells, and the fuel supply manifold comprises: a first section through which the liquid fuel flows in a downward direction from the inlet portion of the conductive end plate above the vertically stacked plurality of cells; a second section which receives the liquid fuel from the first section, and changes a flow direction of the liquid fuel; and a third section which receives the liquid fuel from the second section, and distributes the liquid fuel in an upward direction to each of the plurality of cells.
