摘要： A fuel cell is protected from performance degradation and damage by determining when an ion exchange resin filter needs replacement before the occurrence of an increase in the electric conductivity of water used in the fuel cell system. The replacement time of the ion exchange resin filter 11 is judged by an ion-exchange capacity judging part 152 on the basis of the result of comparing a reference electric conductivity as preset with the electric conductivity of coolant water circulating in a coolant water cycle as measured by an electric conductivity meter 12 a predetermined time after a coolant water pump 14 starts operation.

摘要： A moisture sensor working to measure a moisture content of a specified measurement gas is provided which consists of an electrochemical cell having a first electrode exposed to the measurement gas and a second electrode exposed to a reference gas and a controller. The electrochemical cell outputs an electrical energy arising from chemical reaction of the measurement gas with the reference gas. The controller controls at least one of voltage appearing across and current flowing through the electrochemical cell and uses one of them to measure the moisture content of the measurement gas. This enables the moisture content to be determined free from the humidify of the measurement gas.

摘要： A system which enables fuel cells to be activated at a working point of high energy conversion efficiency. A control unit calculates a required output of an inverter from an input accelerator travel. The control unit specifies an output electric current-output voltage characteristic corresponding to a gas flow rate, obtains a point of highest energy conversion efficiency on the specified characteristic to specify the point as a working point of fuel cells, and computes an output electric power of the fuel cells at the specified working point. The control unit determines an output voltage required to a battery, based on a difference between the calculated required output of the inverter and the computed output electric power of the fuel cells and a state of charge of the battery. The control unit controls a DC-DC converter and regulates the output voltage of the DC-DC converter, so as to cause the battery to generate the output voltage thus determined. The control unit subsequently controls the inverter, so as to cause a motor to consume electric power corresponding to the required output.

摘要： The present application is directed to a gas-generating apparatus (10). Hydrogen is generated within the gas-generating apparatus and is transported to a fuel cell. The generation of hydrogen is regulated automatically by the selective exposure of a catalyst (48) to the fuel mixture depending on the pressure inside the reaction chamber (28) of the gas-generating apparatus. Catalyst sealing mechanisms (40, 42) are provided at least partially within the reaction chamber to regulate the hydrogen pressure and to minimize the fluctuations in pressure of the hydrogen received by the fuel cell.

摘要： A fuel cell system capable of measuring AC impedance comprises: power generation stabilizing means for stabilizing power generation in a fuel cell, and impedance measuring means for measuring the AC impedance after power generation in the fuel cell has been stabilized. Since the AC impedance in a low frequency range is measured after power generation in the fuel cell is stabilized, no external disturbance occurs during measurement, and the AC impedance can be measured with a high degree of precision. Thus, a fuel cell system and a measuring method with which AC impedance can be measured with a high degree of precision can be provided.
