Heat exchanger for fuel cell

A heat exchanger (100) for cooling a fuel cell (10) is provided with multiple fins (132), multiple tubes (131) which are laminated and separated from each other by the fin (132), and at least two tanks (110, 120) which are communicated with the tubes (131) at longitudinal-direction ends of the tubes...

More Information
Summary:A heat exchanger (100) for cooling a fuel cell (10) is provided with multiple fins (132), multiple tubes (131) which are laminated and separated from each other by the fin (132), and at least two tanks (110, 120) which are communicated with the tubes (131) at longitudinal-direction ends of the tubes (131). Cooling water is circulated to flow through the tubes (131), the tanks (110, 120) and the fuel cell (10). The tanks (110, 120) and the tubes (131) are made of resin, while the fins (132) are made of metal. Thus, cooling water which carries electricity can be electrically insulated from the externals by the tanks (110, 120) and the tubes (131), while the cooling capacity of the heat exchanger (100) can be satisfactorily maintained.
