    摘要: A stack for a mixed oxidant fuel cell and a mixed oxidant fuel cell system including the stack. The stack includes at least one membrane-electrode assembly that includes a polymer electrolyte membrane, an anode and a cathode disposed on opposite sides of the polymer electrolyte membrane, and an electrode substrate disposed on at least one of the anode or the cathode; and an oxidant supply path and a fuel supply path that penetrate the membrane-electrode assembly. The oxidant supply path has both ends open, and the fuel supply path has one end open and the other end closed. The stack of the present invention can improve fuel cell efficiency by smoothly supplying a fuel and an oxidant. Particularly, since the stack is configured to supply the fuel and the oxidant without using a pump, it can make a fuel cell small and light.

    摘要: A solid oxide fuel cell is provided. The solid oxide fuel cell has a structure in which a separate thermal expansion member is provided in a current collecting body formed on the inner circumferential surface of a first electrode so that the uniform contact between a support body of the first electrode and the current collecting body can be maintained even though the internal diameter of the support body of the first electrode is changed. Accordingly, the current collection performance of the current collecting body is enhanced through the thermal expansion member between the first electrode and the current collecting body, thereby improving the entire performance of the fuel cell.
