<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing the freezing of a discharge route after starting power generation. <P>SOLUTION: After the power generation is started (S100), the convergence temperature of an oxidizer gas discharge flow path where cathode offgas flows is recognized (S110). In such a case that the convergence temperature is ≤0°C, it is judged that there is the risk of freezing, the flow rate of the cathode offgas is elevated by increasing the rotation speed of an air compressor or the like (S150), and control for inhibiting idling stop control is executed further (S160). Thus, the cathode offgas passing through the oxidizer gas discharge route is discharged to the outside of a vehicle before freezing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
