摘要： This fuel cell system is for suppressing a backflow of water from an exhaust pipe outlet that discharges a reactant-off gas, without decreasing the performance and fuel consumption of a fuel cell, the exhaust pipe being configured to switch between a main discharge pipe and a sub discharge pipe by a switching means to discharge the reactant-off gas. The sub discharge pipe includes a rising gradient portion formed to incline upwards above a gradient of the main discharge pipe and a falling gradient portion formed to incline downwards at the downstream of the rising gradient portion. The switching valve switches to allow the reactant-off gas to be discharged from the main discharge pipe if an amount of reactant-off gas to be discharged is equal to or above a threshold value of an amount of discharge, and allow the reactant-off gas to be discharged from the sub discharge pipe if the amount of reactant-off gas to be discharged is below the threshold value of the amount of discharge.

摘要： A cooling system of a fuel cell is provided with a main cooling flow passage and a bypass cooling flow passage which is arranged parallel with the main cooling flow passage and diverts the same coolant, as flow passages through which coolant flows. A radiator and a coolant circulation pump (WP) and the like are arranged in the main cooling flow passage. Coolant from the main cooling flow passage enters the bypass cooling flow passage and reaches a second heat exchanger via a case of a motor of an ACP and the like. At the second heat exchanger, heat exchange is also performed with a supply gas flow passage, after which the coolant returns to the main cooling flow passage. The manner in which the coolant is distributed can be changed depending on where the coolant is diverted from the main cooling flow passage and the arrangement of the circulation pump.

摘要： A temperature sensor 32 detects the temperature of a coolant circulating in a coolant supply system 3 of a fuel cell 20. A control unit 80 monitors the temperature detected by the temperature sensor 32. When the temperature of the coolant is higher than a target temperature, the control section switches a rotary valve 34 to a radiator-side flow path so that a radiator 33 cools the coolant, and when the temperature of the coolant is lower than the target temperature, the control section switches the rotary valve 34 to a bypass-side flow path to raise the temperature of the coolant through FC generation so that the temperature detected by the temperature sensor 32 is equal to the target temperature. During the process above, in a low temperature environment, the target temperature is raised to a temperature that is higher than a target temperature during a normal operation, while a heater 130 heats the coolant. Through the above processing, the temperature inside the fuel cell can be prevented from decreasing excessively even in the low temperature environment.
