摘要： A controller of a fuel cell system includes an anode gas replacement apparatus, a stoppage time detection apparatus, and a cathode gas flow rate control apparatus. The anode gas replacement apparatus replaces hydrogen in an anode gas channel using an anode gas supply apparatus. The stoppage time detection apparatus detects a stoppage time during which operation of the fuel cell stack is stopped. When the anode gas replacement apparatus replaces the hydrogen, the cathode gas flow rate control apparatus changes the flow rate of the cathode gas supplied from the cathode gas supply apparatus depending on the stoppage time.

摘要： A fuel-cell system is provided, which includes a fuel cell, a reactive-gas supply unit and a control unit. The reactive-gas supply unit supplies the reactive gases to the fuel cell. The control unit includes an average stoichiometric flow-ratio calculation part and a reactive-gas reduction part. The average stoichiometric flow-ratio calculation part calculates an average stoichiometric flow ratio by averaging stoichiometric flow ratios. A stoichiometric flow ratio is a ratio of an amount of the reactive gases supplied to the fuel cell with respect to a required amount of the reactive gases of the fuel cell in accordance with a required amount of power generation. When the average stoichiometric flow ratio is equal to or greater than a first predetermined value, the reactive-gas reduction part reduces the amount of the reactive gases supplied to the fuel cell so as to lower the stoichiometric flow ratio.

摘要： A start-up method for a fuel cell system that includes a fuel cell that carries out power generation by the electrochemical reaction between a fuel gas and the oxygen gas in the air; a fuel gas discharge path and a fuel gas supply path that are connected to the fuel cell; a fuel gas circulation path in which the fuel gas discharge path merges with the fuel gas supply path; and a purge valve provided on the fuel gas circulation path in order to discharge the circulating fuel gas from the fuel gas circulation path. The method includes the steps of opening the purge valve at the same time that the fuel gas is supplied to the fuel cell and replacing the nitrogen gas that originates in the air and is present in the fuel gas circulation path by fuel gas; and closing the purge valve after the nitrogen gas in the fuel gas circulation path has been replaced by the fuel gas.

摘要： A switchback unit has a switchback roller which receives a paper sheet conveyed in a first direction into a nip for forward rotation and backwardly rotates the paper sheet after stopping the paper sheet to feed the paper sheet to a second conveyance path. When the conveyance of the paper sheet stopped on the way to the switchback section is resumed, control is performed so that the switchback roller is forwardly rotated until a sensor detects the tip of the paper sheet, and then the switchback roller is stopped and backwardly rotated.

摘要： It is intended to provide a signal detection circuit and a signal detection method capable of preventing influences of variations in transistor characteristics, occurrence of yield degradations of the signal detection circuit and capable of detecting differential input signals at high speed. The signal detection circuit 4 comprises an amplifier section 1, a comparator section 2, and an output section 3. Differential input signals and differential reference voltages are differential-amplified by differential amplifiers 10, 11 of identical circuit structure provided in the amplifier section 1. The relationship of degree between differential input signals and differential reference voltages after differential amplification are compared in comparators 12 and 13 of the comparator section 2. High level comparison result signals CPH are output from the comparator 12 through node N6 during period in which at least one of amplified data plus signals GDP and amplified data minus signals GDM is higher than amplified high reference voltages GRH. In an integration circuit 21, integration of comparison signals COMP is performed for performing noise eliminating operations and for outputting detection signals HS_ENV_OUT.
