<P>PROBLEM TO BE SOLVED: To provide a fuel cell heat exchanger that is compact and can be installed in a system. <P>SOLUTION: A fuel cell heat exchanger has a hollow and flat shell member 1 in which a heat exchanging medium passes and a plurality of pipes 17 in which combustion gas passes is lined and arranged in the inside of the shell member 1. Reinforcing ribs 8, 9, 10, 11 protruding inside are formed in a flat parts 2a, 4a of the shell member 1, the reinforcing ribs 8, 9, 10, 11 are formed along the flowing direction of the heat exchanging medium. A supply opening 12 and a discharge opening 6 of the heat exchanging medium are arranged in both end sides of the shell member 1, an end of the shell member 1 of the discharge opening 6 side is formed protruding upward, further, the end of the shell member 1 of the supply opening 12 side is protruded downward. Both ends of the pipe 17 are inserted and fixed into both partitioning members 14, 16 closing both ends of the shell member 1, the partitioning members 14, 16 are covered with cap members 18, 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
