摘要： The measurement precision of a current detector of the fuel cell in a fuel cell system is improved. Where the fuel cell system 20 has not started operation, the vehicle 10 is operating under regenerative operation, the fuel cell 21 is operating under intermittent operation, or operation of the fuel cell system 20 has ended, the output terminal voltage of the fuel cell 21 is set to the OCV value of 400V via the DC/DC converter 31. As a result, even where the status of the fuel cell 21 changes from operating to stopped, the value of the current flowing over the power supply lines 411 can be immediately and reliably set to 0 A. The control unit 60 then obtains the current value Ad from the fuel cell current sensor 413 (step S150), and determines the offset correction value Ac needed in order to cancel the drift amount (i.e., in order to perform zero-point correction).

摘要： A gas detection system functions to detect a specific gas present in a certain space. The gas detection system includes a gas concentration detector arranged to detect concentration of the specific gas as a gas concentration. The gas detection system also has a determination module configured to determine whether the gas concentration detected by the gas concentration detector exceeds a set threshold value. In response to input of a checking instruction for checking up the gas concentration detector into the determination module, the determination module uses a threshold value for checkup purpose, in place of the set threshold value. This arrangement effectively enhances the convenience in the process of checking up the gas concentration detector.

摘要： A gas detection system is configured to detect a preset gas in a predetermined space. The gas detection system includes a gas concentration detector constructed to detect a gas concentration of the preset gas, a recording assembly, a notification module, and a decision module. When the gas concentration detected by the gas concentration detector is higher than a preset first reference value, the decision module controls the notification module to give notice. When the detected gas concentration is higher than a preset second reference value but is lower than the preset first reference value, on the other hand, the decision module controls the notification module to give no notice but record a specific piece of information into the recording assembly. This arrangement of the gas detection system enables the user to readily detect deterioration of a device utilizing a fuel, for example, fuel cells.

摘要： An object of the present invention is to reduce the period of time required to stop a fuel cell system and to suppress freezing of a fuel cell. The fuel cell system includes a controller that controls operations of a fuel cell, and the controller operates the fuel cell in a dry condition according to a state quantity (e.g., impedance) of the fuel cell in operation. The controller can operate the fuel cell in a dry condition before a system stop command is issued. In addition, the controller can switch an operation of the fuel cell from a dry condition to a wet condition when a required output of the fuel cell or a vehicle speed of a vehicle equals or exceeds a predetermined value.

摘要： A fuel cell system comprises a fuel cell, a reactant gas supply device, and a capacitor which supplies a power to various devices when the fuel cell is in a temporary power generation stop state. The fuel cell system drives the reactant gas supply device based on a predetermined current instruction value to supply a reactant gas to the fuel cell, thereby generating the power. Such a fuel cell system comprises a control device which judges whether or not the current instruction value is below a water balance zero current value when the water content of the fuel cell is below a predetermined threshold and the stored electric charge of the capacitor is a predetermined threshold or more. If affirmative judgment is obtained, the control device switches the power generation state of the fuel cell to the temporary power generation stop state.
