摘要： A fuel cell system includes a fuel cell stack (1) comprising an anode (fuel electrode) (1a) and a cathode (oxidizer electrode) (1b), and a system startup run is conducted at the system startup to bring the fuel cell stack (1) into a power extractable state (idle state). In the fuel cell system, air supply flow is controlled so that air in an amount larger than a reference flow required to bring the fuel cell stack (1) into the power extractable state, is supplied to the cathode (1b) over a preset time from the start of air supply to the cathode (1b), by estimating an amount of hydrogen present on the cathode (1b), deciding an air supply flow increment to commensurate with the estimated hydrogen amount, and controlling an air supply flow, whereby air at a flow rate provided by adding the decided increment to the reference flow, is supplied to the cathode (1b) during the system startup run, thereby allowing to effectively restrict a disadvantage in that a high concentration of hydrogen is wasted during the system startup run, without deteriorating the efficiency of the fuel cell system.

摘要： PROBLEM TO BE SOLVED: To provide a water storage tank capable of starting early draining while detecting an exact water level without defrosting the whole inside of the tank. SOLUTION: A separation wall 23 is provided for separating a water storage tank body into a water level detection part at an inside part and a water storage part at an outside part. A water-level sensor 11 is provided inside the separation wall 23. A communicating hole 25 at a position higher than an uppermost water level of the water storage tank body and a communicating hole 26 at a position lower than a lowermost water level are provided on the separation wall 23. The inside of the separation wall 23 is connected to a drain hole 29 and a drain channel 30. COPYRIGHT: (C)2009,JPO&INPIT
