According to one embodiment, a vehicle-use storage battery system includes a storage battery, a main circuit, a circuit breaker, a storage battery management unit, a first determiner, and a second determiner. The main circuit is electrically connected to the storage battery. The circuit breaker is disposed between the storage battery and the main circuit to make or break the electrical connection therebetween. The storage battery management unit manages an operating state of the storage battery. The first determiner determines whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker. The second determiner determines, on the basis of at least one of operating states of the storage battery management unit, the first determiner, and the circuit breaker, whether to break the electrical connection between the storage battery and the main circuit by means of the circuit breaker.

Vehicle-use storage battery system

According to one embodiment, a vehicular storage battery device includes a housing, battery boxes, and a common cooling passage. The battery boxes are disposed in the housing. Each of the battery boxes houses an electric cell as a vehicle power source and includes a heat transporting part transporting heat generated in the battery box to outside of the battery box. The common cooling passage is disposed in the housing. The common cooling passage is provided with an inlet for taking in a fluid and an outlet for discharging the fluid having passed through the passage. The inlet and the outlet are open in a direction different from a traveling direction of the vehicle. The heat transporting part of each of the battery boxes is exposed to inside of the passage.

Vehicular storage battery device

In electronic equipment using a fuel cell as a power source, an antenna and a fuel cell, which are provided in a lower case of a main body receiving electronic parts, are arranged at a given distance from each other. An acceptable communication state can be established in the electronic equipment.

Electronic equipment

A PDA, which functions as an electronic unit, includes power supply which includes a fuel cell unit and an auxiliary power supply which is charged by an output of the fuel cell unit. A non-use state of the PDA is detected by non-use detection unit. Upon detection of the non-use state by the non-use detection unit, the output from the fuel cell unit is stopped and an output of the auxiliary power supply is shut off.

Electronic apparatus and fuel cell system

A coupler including a nozzle and a socket. The nozzle includes a nozzle body, a movable pin, and a first supporting member. The movable pin is made retractably movable in the axial direction in a nose portion to open and close the channel inside the nozzle. The socket includes a housing, a collar, a ring-like packing, a valve stem, a valve head, and a second supporting member. The valve stem is made retractably movable in the socket in the axial direction to open and close the channel inside the socket. All portions or components which contact liquid fuel in the coupler are formed solely of rubber and/or plastics.
