Abstract: A vehicle 1000 is equipped with a fuel cell system 100 and a secondary battery as power sources. A water level of water present on a water-covered road surface is measured by a water level sensor 72. When the measured water level reaches or exceeds a preset threshold value, drive control of the vehicle 1000 stops power generation by a fuel cell stack 10, closes a discharge valve 62, and enables the vehicle 1000 to be driven with output power of a motor that is actuated with electric power from the secondary battery. This arrangement effectively prevents a damage or failure of the fuel cells mounted on the vehicle moving on the water-covered road.

Abstract: A vehicle is equipped with fuel cells that is fastened to multiple side frames 810 arranged in parallel to each other and along a moving direction of the vehicle. The vehicle includes a support assembly arranged to span between the multiple side frames 810, a first fixation unit arranged to fasten the support assembly to the respective side frames 810, and a second fixation unit arranged to fix the fuel cells on the support assembly. This arrangement desirably reduces the influence of an external force applied to the fuel cells mounted on the vehicle and prevents an increase in total weight of the vehicle or a decrease in mounting space of the fuel cells.

Abstract: A vehicle 1000 has two pipings 60 and 62 arranged to discharge an exhaust gas from a fuel cell stack 10 to the outside of the vehicle 1000. An outlet provided at an end of the piping 60 is located at an underfloor position in a rear portion of the vehicle 1000, while an outlet provided at an end of the piping 62 is located at a roof rear end of the vehicle 1000. When the outlet provided at the end of the piping 60 is blocked or when there is a potential for such blockage, the outlet provided at the end of the piping 62 is used to discharge the exhaust gas from the fuel cell stack 10 to the outside of the vehicle 1000. This arrangement ensures continuous drive of the vehicle 1000 even in a specific environment where any of various obstructing objects as the cause of blockage of the outlet is present in the surroundings of the vehicle 1000.

Abstract: An ion exchanger comprises an ion exchange cartridge, and an ion exchanger bracket for connecting the ion exchange cartridge to a cooling water path to thereby hold the ion exchange cartridge so as to be freely removed. The ion exchanger bracket is provided at a position closer to the front end portion of the fuel cell vehicle, the position being on the side surface of the sub-frame. The cooling water path, connected to the ion exchanger bracket, is arranged so as to reach the motor room, penetrating the sub-frame. Also, because the ion exchanger is mounted in a space surrounded by the rear side of the bumper and an inner fender covering the rear side of the fender and a tire house, the ion exchange cartridge becomes available to be taken out when a part on the front side of the inner fender is removed.

Abstract: In a motor vehicle equipped with a fuel cell (10), inflow of liquid from outside into the fuel cell (10) is restrained. When it is estimated that there is a risk of liquid flowing into the fuel cell (10) from the gas discharge opening (16) via a gas channel, the exhaust pressure of gas discharged from the gas channel is increased, or passage through the gas channel is shut.

Abstract: An image forming roller according to an aspect includes a shaft, and an electrically conductive elastic layer provided to cover an outer circumferential of the shaft and having a polished surface. The shaft is made of a resin composition containing an aromatic polyamide, a glass fiber, an electrically conductive material and optionally an aliphatic polyamide, and exhibits a bending strength of 250 MPa or higher and a flexural modulus of 15 GPa or higher.

Abstract: A small-sized electronic instrument such as an electronic wrist watch and others in which a plurality of parts are stacked and firmly held together by tightening a screw. The electronic instrument includes a base plate and a screw housing portion, which are integrally molded of a hard plastic material. The screw housing portion includes a bore formed therethrough and adapted to receive a self-tapping screw. When the self-tapping screw is threadingly received in the bore of the screw housing portion, a plurality of parts stacked around the screw housing portion are firmly tightened and held together. The screw housing portion has a shoulder including a step formed therein at the middle portion between the opposite ends. On assembly, the step engages one of the stacked parts. Even if the screw housing portion is pulled upwardly by the tightened self-tapping screw, the part sandwiched between the self-tapping screw and the step limits the upward movement of the screw housing portion on tapping.
