Abstract: A fuel cell system includes a fuel cell, a circuit, a pump, a pressure regulating valve, and a control apparatus. The fuel cell includes a plurality of membrane electrode assemblies and a separator. The separator has a gas channel and a coolant channel. The circuit is coupled to the coolant channel and allows a coolant to circulate therethrough. The pump delivers the coolant toward the coolant channel. The pressure regulating valve adjusts a pressure of the coolant in the coolant channel. The control apparatus controls a flow rate of the coolant in the coolant channel by controlling a rotational speed of the pump on the basis of a temperature of the fuel cell, and controls the pressure of the coolant in the coolant channel by controlling a position of the pressure regulating valve on the basis of a pressure of gas in the gas channel.

Abstract: A vehicle includes first and second heat exchangers, a shutter member, first and second detectors, and a control device. The first and second heat exchangers are disposed in an engine room. The first heat exchanger is used for cooling of an engine. The second heat exchanger is used for recovery of exhaust heat of the engine. The shutter member opens and closes a grille opening in a front portion of the engine room. The first detector detects a feed forward system parameter indicating a sign of a load increase the first exchanger or the second heat exchanger. The second detector detects a feedback system parameter indicating that a load in the first exchanger or the second heat exchangers has increased. The control device controls opening and closing of the shutter member and adjusts an opening degree of the shutter member based on the feed forward and feedback system parameters.
