<P>PROBLEM TO BE SOLVED: To provide a fuel battery and a fuel battery system using the fuel battery capable of effectively radiating the heat generated in a solid polymer fuel battery to outside with simple configuration. <P>SOLUTION: Each of a plurality of first heat pipes 4a is structured of a conductive pinched part 41 pinched between each two fuel battery cells 20 and a projection 42 protruded outside from the space between the adjacent fuel cells 20. The projection 42 is structured of a protruded root part 421 extended in the same direction as the conductive pinched part 41, and a folded part 422 extended in parallel with a side face 28 of a stack 2. In the conductive pinched parts 41, operating liquid inside the fuel cells 20 is boiled and evaporated by their radiation heat to move toward the folded parts 422 at a low-temperature end, and cooled at the folded part, and the radiation heat is transferred to second heat pipes 6 installed outside the stack 2, and transferred from the second heat pipes 6 to a heat exchanger 7. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
