摘要： A method utilizing the resistance of the electrolytic membrane of a fuel cell is known conventionally as a method for detecting abnormality occurring in the fuel cell. As shown on FIG. 4, resistance of the electrolytic membrane increases as the temperature thereof decreases or the moisture content thereof decreases (i.e. dry state), and decreases as the temperature increases or the moisture content increases (i.e. wet state), and thereby it was difficult to judge whether a deterioration in performance or a simple drop in performance has occurred by simply detecting an increase in resistance. A criterion for judging a deterioration in performance of a fuel cell based on the resistance of an electrolytic membrane is thereby set higher as the electrolytic membrane approaches a dry state and temperature thereof decreases and set lower as the electrolytic membrane approaches a wet state and the temperature thereof increases. Consequently, a deterioration in performance of a fuel cell can be judged easily regardless of the operating state thereof.
摘要翻译：利用燃料电池的电解质膜的电阻的方法通常被认为是用于检测在燃料电池中发生的异常的方法。如图所示。如图4所示，随着温度降低或水分含量降低（即干燥状态），电解质膜的电阻增加，随着温度升高或湿度增加（即湿润状态）而降低，因此难以判断电解质是否通过简单地检测电阻的增加，发生性能的恶化或性能的简单降低。由于电解质膜接近干燥状态并且其温度降低并且随着电解质膜接近潮湿状态而降低，所以基于电解质膜的电阻来判断燃料电池的性能劣化的标准被设定得更高其增加。因此，能够容易地判断燃料电池的性能的劣化，而与其工作状态无关。

摘要： A fuel cell system capable of suppressing noise caused by backflow of air when a compressor stops. Also, there is provided a fuel cell vehicle provided with this fuel cell system. A fuel cell system includes a fuel cell and a compressor that compresses air taken in from outside and supplies compressed air to the fuel cell. Operation of the compressor is stopped after a pressure difference between an upstream side and a downstream side of the compressor has become equal to or smaller than a predetermined value by using a control unit. In this case, the predetermined value can be a pressure difference corresponding to a predetermined noise level.

摘要： A power supply system is provided for supplying power to a first drive device and a second drive device functioning as a drive source of a moving body. A fuel cell and a storage battery device are connected via a power conversion device. The fuel cell can supply power to the first drive device and the storage battery device can supply power to the second drive device, respectively, without using the power conversion device. When an output request from the moving body is a normal output request, power is supplied to each of the drive devices by the fuel cell and the storage battery device, respectively. Only when power to be supplied to the first drive device as in the output request from the moving body is greater than an amount of power that can be generated by the fuel cell, that power supply from the storage battery device to the first drive device via the power conversion device is permitted. Thus, in a power supply device that is formed of a plurality of power supply devices connected via a power conversion device, it is possible to avoid, to the extent possible, decrease of efficiency of power supply to a drive device of a moving body.

摘要： A compact type bar code reader for detecting a bar code symbol provided on a surface of an article. The bar code reader includes a laser beam generation unit for generating the laser beam to be irradiated onto a bar code symbol, and a focus unit for determining a focus of the laser beam, and a scanning pattern forming unit for forming various scanning patterns of the laser beam. The bar code reader also includes a light reflection unit for reflecting the laser beam to and from the bar code symbol, a light collection unit for collecting the laser beam reflected from the bar code symbol, and a light reception unit for receiving the laser beam collected by the light collection unit, and converting it to an electrical signal. The above units are included in a casing so that the laser beam generation unit, the focus unit, the light collection unit, and the light reception unit are arranged at a lower portion of the casing, and the scanning pattern forming unit and light reception unit are arranged at a lower portion of the casing. The light path of the laser beam is formed in such a way that an emitted light path from the laser beam generation unit to the bar code symbol becomes considerably long, and a reflected light path from the bar code symbol to the light reception unit becomes shorter than the emitted light path.

摘要： There is disclosed a converter controller which can simply and early detect an abnormality of an auxiliary circuit constituting a soft switching converter. On turning off a first switching element, a controller detects a voltage between both the ends of a snubber capacitor and a voltage between both the ends of the first switching element, to obtain a difference voltage. The controller compares the obtained difference voltage with a voltage threshold value stored in a memory (not shown) to judge whether or not the difference voltage is larger than the voltage threshold value. When the difference voltage is smaller than the voltage threshold value, the controller judges that an auxiliary circuit is normal, to end processing, whereas when the difference voltage is not less than the voltage threshold value, the controller judges that a failure (an open failure) occurs in the auxiliary circuit, to shift to a fail safe operation, thereby ending the processing.
