The vehicle control apparatus configured to control a vehicle includes a fuel cell configured to supply electric power to the vehicle; an air conditioning mechanism having a heater core; a first medium circuit; a radiator installed in the first medium circuit; a bypass circuit formed in the first medium circuit to make a bypass flow of the cooling medium bypassing the radiator; a regulation valve installed in the first medium circuit to regulate a ratio of a flow rate of the cooling medium going through the radiator to a flow rate of the cooling medium going through the bypass circuit; a second medium circuit; a cooling medium circulation pump installed in at least one of the first medium circuit and the second medium circuit; a temperature acquisition module; a warm-up controller; and a state switchover structure.

Vehicle control apparatus and vehicle control method

A cooling system is provided. The cooling system includes: a fuel cell; a cooling circuit configured to circulate a coolant medium to cool the fuel cell; an air conditioning circuit configured to circulate the coolant medium, the air conditioning circuit having a heat exchanger to execute heat exchange between the coolant medium and air to be sent to a room; a switching unit configured to switch between a connected state and a disconnected state; and a controller configured to control operation of the cooling system, wherein when the controller switches a state of the cooling system from the disconnected state to the connected state, irrespective of conditions in the cooling system, the controller executes operation of the cooling system in a flow rate control mode whereby the ratio (LL) of a first flow rate (L) to a second flow rate (L) is set to or above a prescribed value, wherein the first flow rate (L) represents the flow rate of the coolant medium flowing through the cooling circuit, and the second flow rate (L) represents the flow rate of the coolant medium flowing through the air conditioning circuit.

In the hydrogen supply device for producing and supplying hydrogen to a fuel cell, a reforming section has a rotary thermal storage through which low and high temperature passages pass. Reforming material is supplied to the low temperature fluid passage on an upstream side of the first rotary thermal storage. A combustion gas supply section for generating and supplying a combustion gas is located in the high temperature fluid passage on a downstream side of the first rotary thermal storage. With the hydrogen supply device mentioned above, the first rotary thermal storage rotates to move alternately between the low and high temperature fluid passages so that, in the reforming section, the reforming material flowing in the low temperature fluid passage is catalytically reformed to a reformed gas containing hydrogen upon receiving combustion heat of the combustion gas flowing in the high temperature fluid conduit.

Hydrogen supply device

A fuel cell system includes a fuel cell (FC stack), an inflow passage valve provided in a hydrogen inflow passage through which hydrogen is supplied to the FC stack, and a discharge passage valve provided in a hydrogen discharge passage through which hydrogen containing gas is discharged from the FC stack as exhaust gas. In the fuel cell, hydrogen is supplied to the FC stack intermittently in accordance with an amount of hydrogen consumed in the FC stack, by controlling opening and closing of the inflow passage valve and the hydrogen discharge valve.

According to the present invention, a catalyst combustion apparatus includes a ring-shaped catalyst body for catalytically burning the mixture of the fuel and the air, which is disposed in a combustion cylinder. In the combustion cylinder, a fuel nozzle and an inlet for the air are disposed at one end side of the catalyst body, and the premixing chamber is formed at the other end side. The fuel and the air are supplied from one end side of the catalyst body through a through-hole formed at a center portion of the catalyst body and is mixed in the premixing chamber. In the premixing chamber, a flow direction of the mixture is turned toward the catalyst body. A part of the exhaust gas is introduced into the air at one end side. In this way, it is possible to simplify and downsize the combustion apparatus, while securing the preheating effect of the air by the circulation of the exhaust gas.
