<P>PROBLEM TO BE SOLVED: To warm up a fuel cell stack using a general heat exchange medium containing no latent heat storage material. <P>SOLUTION: This warming-up device of the fuel cell stack 10 is provided so that heat can be exchanged between the device and cooling water in a fuel cell system equipped with the fuel cell stack 10 and a cooling water system 21 in which the cooling water for exchanging heat with the fuel cell stack 10 passes. The warming-up device is formed by providing the latent heat storage material 30 generating heat by the change of phases in piping 24 with the heat storage material attached in the cooling water system 21. When starting the warming-up device, it is warmed by introducing the cooling water to the piping 24 side, and the warmed cooling water is returned to the fuel cell stack 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
