Abstract: A motor-driven compressor is installed in a fuel cell vehicle to supply air to a fuel cell. The motor driven compressor includes a rotation shaft, an electric motor, a compression unit that compresses air, a housing that includes a motor chamber and a compression chamber, and a seal member that restricts a flow of a fluid between the motor chamber and the compression chamber. The housing includes an inlet and an outlet. The inlet draws, into the motor chamber, the air-conditioning refrigerant that has passed through the evaporator but has not reached the air-conditioning compressor as a low-temperature refrigerant. The outlet discharges the low-temperature refrigerant, which is drawn from the inlet into the motor chamber, out of the motor chamber.

Abstract: A bonding method includes bonding a pair of members together made of conductive material and having bonding surfaces which are not positioned on the same plane. In the bonding method, the bonding surfaces of the members to be bonded are positioned to face each other, an electric current is supplied from one of the members to be bonded to the other for carrying out resistance heating while the pair of members to be bonded are slid relative to each other. In this way, the bonding surfaces are bonded to each other. Split or partition surfaces that form a hollow passage and extending along the axis of the hollow passage are set as the bonding surfaces which are not on the same plane.

Abstract: Joining surfaces (2a, 2b) of a pair of conductive joining members (1a, 1b) to be joined to each other are caused to face each other, and while one of the joining members (1a, 1b) is slid relative to the other of the joining members (1a, 1b), a current is passed from one of the joining members (1a, 1b) to the other of the joining members (1a, 1b) so as to cause resistance heating. Abrasion, plastic flow, and material diffusion therefore occur in high surface-pressure sections of the joining surfaces (2a, 2b), and the joining surfaces (2a, 2b) are joined together while current concentration locations are varied from moment to moment.

Abstract: Provided is a fuel cell system which can properly control a refresh operation. A controller controls the refresh operation so that an output voltage does not exceed an avoidance voltage even after the refresh operation. Specifically, the controller estimates the output voltage after the refresh operation from the output voltage before the refresh operation and controls execution of the refresh operation so that the estimated output voltage after the refresh operation does not exceed the avoidance voltage. For example, if before the refresh operation, when judging that the estimated output voltage after the refresh operation does not exceed the avoidance voltage, the controller executes the refresh operation.

Abstract: There is provided a fuel cell system capable of warming up a fuel cell while inhibiting generation of a rush current. A control device switches the connection/disconnection between a fuel cell and a short circuit by a shorting relay. The control device spends, before switching the shorting relay from disconnection to connection during starting at a low temperature, an oxidizing gas remaining in the cathode of the fuel cell by driving auxiliary devices to generate an oxidizing gas-deficient state. Then, the control device switches FC relays from ON to OFF and the shorting relay from OFF to ON to thereby complete the preparation for supplying a short-circuit current.
