    摘要： A fuel cell power system comprises at least one fuel cell and a cooling circuit in which coolant is intended to circulate for regulating temperature of the at least one fuel cell. The cooling circuit comprises a ram air heat exchanger, and the fuel power system further comprises a controller configured for: regulating temperature of the coolant according to a first target temperature in nominal operations; when receiving an event, referred to as first event, indicating that the fuel cell power system shall prepare for highly demanding electrical energy situation or cooling low availability situation, regulating temperature of the coolant according to a second target temperature lower than the first target temperature. Thus, dimensioning of a ram air system which includes the ram air heat exchanger is reduced.

    摘要： A fuel cell unit (10) includes a fuel cell stack (20) having a coolant channel (23) inside where coolant flows in one direction, and having a first surface (27) parallel to a direction in which the coolant channel extends; a boost converter (40) disposed across a gap from the first surface (27) without being partitioned by a heat shielding member, the boost converter (40) including a current sensor (43) and a capacitor (45) disposed following the first surface; and a case (30) that accommodates the fuel cell stack (20) and the boost converter (40) in a same space, wherein at least one of the current sensor (43) and the capacitor (45) is disposed on an upstream side from a middle of the coolant channel, in the direction in which the coolant channel extends.

    摘要： A fuel cell system (15) includes: a fuel cell stack (600); a first cooling medium circuit (505) through which a cooling medium for cooling the fuel cell stack (600) flows; an ion exchanger (540) that removes ions in the cooling medium; a second cooling medium circuit (705) in which the average ion concentration of the cooling medium is lower than that of the cooling medium in the first cooling medium circuit (505); a switching valve (740) that switches between a flow state and a low flow state; a pump (725) configured to cause the cooling medium in the second cooling medium circuit (705) to flow into the first cooling medium circuit (505); and a control unit (900) that, when a stop period of the fuel cell system (15) is longer than a reference period, drives the pump (725) with the switching valve (740) switched to the flow state after the instruction to start the fuel cell system (15) is input.
