<P>PROBLEM TO BE SOLVED: To provide a heat exchanger for exhaust heat recovery with heat exchange effectiveness improved, and to provide a fuel cell system equipped with it. <P>SOLUTION: The heat exchanger for exhaust heat recovery 1 is provided with a heat exchange unit 12 for recovering heat of exhaust gas exhausted from a fuel cell, and a storing container 2 for storing the heat exchange unit 12. The storing container 2 is structured of a cylindrical container 3 formed of heat-resistant resin inide which the exhausted gas passes through, and lid-shape members 4, 5 arranged at apertures on both sides of the cylindrical container 3 and closing the apertures. The cylindrical container 3 consists of an inner wall 6 and an outer wall 7, and has a dual structure consisting of a storing part 8 storing the heat exchange unit 12 formed by the inner wall 6 and a hollow part 9 formed by the inner wall 6 and the outer wall 7. <P>COPYRIGHT: (C)2008,JPO&INPIT |
