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： A fuel cell power plant includes an energy storage system connected in parallel with a fuel cell system. The fuel cell system includes a controller, a fuel flow system, an air flow system, and an internal water management system. The controller is operable to receive, as inputs, the energy storage system state of charge and the power demand from an electric load. The controller is further operable to determine a power split set point and execute commands, as output, to control operation of the air flow system, wherein the air flow system actively regulates the proportion of current flow between the fuel cell system and the energy storage system to meet the power demand of the electric load.

摘要： A power controlling apparatus includes a secondary battery (2) connected to an electrical device (4), and a fuel cell (3) connected to the electrical device (4) and the secondary battery (2). The fuel cell (3) has two non-generating modes including an idling mode and a halt mode, the fuel cell (3) suspending generation of power while being supplied with fuel in the idling mode, the fuel cell (3) stopping generation of power without fuel supply in the halt mode. The power controlling apparatus further includes a remainder estimator (11) to calculate the remaining number of starts representing the remaining number of available starts of the fuel cell (3), and a controller (16) to control the fuel cell (3) to be one of the two non-generating modes during a non-charging mode of the secondary battery (2), based on the remaining number of starts calculated by the remainder estimator (11).

摘要： An apparatus for measuring an impedance of a fuel cell is configured to: output an AC current to a fuel cell; and adjust an impedance so that an impedance between the fuel cell and a load device becomes higher than an impedance between a secondary battery and the load device at a frequency of the AC current outputted to the fuel cell. The apparatus is also configured to: adjust the AC current so that a positive-electrode side AC potential difference matches a negative-electrode side AC potential difference, the positive-electrode side AC potential difference being a difference between an electric potential of the fuel cell on a positive electrode side and a middle electric potential, the negative-electrode side AC potential difference being a difference between an electric potential of the fuel cell on a negative electrode side and the middle electric potential; and calculate an impedance of the fuel cell on the basis of the adjusted AC current and at least one AC potential difference of the positive-electrode side AC potential difference and the negative-electrode side AC potential difference.
