摘要： A fuel cell system installed in a vehicle includes: a fuel cell; a secondary battery; a load including a drive motor and an air compressor; a fuel cell converter; a secondary battery converter; a failure detection unit; a first state determination unit; a reverse rotation detection unit; and a control unit. The control unit performs a limp-home traveling control that supplies electric power from the secondary battery to the drive motor when the secondary battery converter fails. When the vehicle is not in the first state, the control unit prohibits regeneration of the drive motor. When the vehicle is in the first state, the control unit supplies a reaction current to the air compressor. When the reaction current is applied and a reverse rotation of the air compressor is detected, the control unit does not apply the reaction current thereafter.

摘要： In one or more embodiments of the novel aircraft fuel cell system without the use of a buffer battery, the fuel cell and compressor would be sized sufficiently larger for the intended application, allowing the compressor to change speeds much faster. This in turn would allow power outputs to change much quicker. If power outputs can change as quickly as the application dictates, then a buffer battery is not necessary. In one or more embodiments, because the system is mostly electronically controlled, software can be written to protect the fuel cell from instantaneous power spikes. If a large power output is suddenly requested of the fuel cell, the software can smooth out the demand curve to provide an easier load profile to follow.

摘要： A fuel cell system includes a fuel cell, a supercharger, a coolant circuit, a pump controller, and a pressure regulating mechanism. The supercharger applies pressure to cathode gas and supplies the cathode gas to the fuel cell. The coolant circuit has a coolant circulation pump and a cooler and circulates a coolant to be supplied to a coolant channel in the fuel cell. The pressure regulating mechanism regulates coolant pressure in the fuel cell. The pump controller controls a rotation speed of the pump in accordance with a heat release amount required by the fuel cell and controls the pump in a range lower than or equal to an upper limit for the rotation speed set based on one or both of inlet coolant pressure of the pump or a correlation value thereof and an inlet coolant temperature of the pump or a correlation value thereof.

摘要： A fuel cell system is equipped with a control unit that controls a rotational speed of the turbo compressor that supplies air to an air supply flow passage and an opening degree of at least one valve that adjusts a flow rate and a pressure of the air supplied to a fuel cell such that an operating point of the turbo compressor becomes a target operating point. The control unit sets the target operating point within an operating point range that is on the higher flow rate side than at least part of a first region where an amount of change in flow rate is larger than a predetermined value when a pressure ratio of the turbo compressor is changed by a predetermined amount at a same rotational speed, on a higher flow rate side than a surging region, when a predetermined condition is fulfilled.
