Oxidant gas flows to the fuel cell stack through an oxidant gas supply channel. Oxidant off-gas is discharged from the fuel cell stack through an oxidant off-gas exhaust channel. A refrigerant is discharged from the fuel cell stack through a refrigerant exhaust channel. An outlet sealing valve is provided in the oxidant off-gas exhaust channel. The outlet sealing valve includes a main body, a valve seat, a valve body, and a refrigerant passage. The main body has a passage through which the oxidant off-gas flows. The valve seat is provided in the passage. The valve body is provided in the passage to be seated on the valve seat to close the passage. The refrigerant passage is branched off from the refrigerant exhaust channel. The refrigerant flows in a vicinity of at least one of the valve seat and the valve body through the refrigerant passage.

Fuel cell system

A vehicle installation structure includes a vehicle frame and an electrical unit. The electrical unit includes at least one first high-voltage electrical apparatus, a cooling structure, and a bracket. The cooling structure is to cool the at least one first high-voltage electrical apparatus. The cooling structure has a duct member made of a non-metal material. The bracket is attached to the vehicle frame. The at least one first high-voltage electrical apparatus is connected to the bracket via the duct member with a connecting member.

Vehicle installation structure

An electrically driven vehicle includes a first electrical apparatus, a second electrical apparatus, a low-voltage electrical circuit, a relay terminal block, and a high-voltage cable. The low-voltage electrical circuit is connected to the first electrical apparatus. The relay terminal block is positioned in the low-voltage electrical circuit so as to be electrically connected to the first electrical apparatus. A space is provided between the relay terminal block and the first electrical apparatus. The high-voltage cable is connected to at least one of the second electrical apparatus and the first electrical apparatus and is provided to pass through a space.

Electrically driven vehicle

An electrically driven vehicle includes a vehicle frame, an electrical unit, a first fixing member, and a second fixing member. The vehicle frame includes a lower frame and an upper frame. The electrical unit is connected to the lower frame and the upper frame. A lower portion of the electrical unit is connected to the lower frame with a first holding force in a vehicle up-down direction via a first fixing member. An upper portion of the electrical unit is connected to the upper frame with a second holding force in a vehicle front-rear direction via a second fixing member. The second holding force is smaller than the first holding force. The second fixing member is provided at a position in which a load applied in the vehicle front-rear direction is exerted to the second fixing member more than to the first fixing member.

A variable lift valve operating system for an internal combustion engine, including a variable lift mechanism capable of changing a lift amount of an engine valve in accordance with rotation of a control shaft rotatably supported in a cylinder head, and an actuator which has an electric motor and power transmission means interposed between the electric motor and the control shaft, and which is connected to the control shaft. The actuator is constructed to have an oilless structure without oil supply, thereby always stably and rotationally driving the control shaft.

Variable lift valve operating system for internal combustion engine

In a variable lift valve operating system for an internal combustion engine, an actuator for rotatably driving a control shaft of a variable lift mechanism is mounted on an engine body. The actuator includes an electric motor, a deceleration mechanism, a transmission mechanism interposed between the control shaft and the deceleration mechanism, and a default mechanism. A deceleration mechanism accommodation part for accommodating the deceleration mechanism and a default mechanism accommodation part for accommodating the default mechanism are formed in a casing of the actuator so as to sandwich therebetween a thermally vulnerable part which is directly connected to the control shaft. Therefore, it is possible to enhance the degree of freedom of amounting position of the actuator while heat damage is prevented from generating in the thermally vulnerable part of the actuator.
