The fuel cell system includes a fuel cell for generating electrical power after causing an anode to receive a hydrogen-containing anode gas and causing a cathode to receive an oxygen-containing cathode gas; an exhaust gas valve provided downstream of the fuel cell in a gas circulation system that supplies an anode gas to the fuel cell; a regulator that is provided upstream of the fuel cell in the gas circulation system and raises gas pressure in the gas circulation system; and an ECU that opens the exhaust gas valve, with the gas pressure kept raised to a level higher than in normal times by use of the regulator. As a result of this, it is possible to increase the gas flow rate and flow velocity within the fuel cell, and it becomes possible to increase the discharge amount of moisture stagnating within the fuel cell.

摘要： The invention provides a method and an apparatus for plasma cutting which can produce a cut product having less dross, affixed thereto, and a clear cut surface, and which are capable of high-speed performance even at the time of the piercing operation. To this end, during the time of the piercing operation, an oxidative gas (O.sub.2) is used as the plasma gas, and at the time of the cutting operation a non-oxidative gas (N.sub.2) is used as the plasma gas to cut a workpiece (6). In addition, when shifting from the piercing operation to the cutting operation, the supplying of the non-oxidative gas (N.sub.2) can be started before the supplying of the oxidative gas (O.sub.2) is stopped.

摘要： A gas/liquid separation device is connected to a discharge valve which can discharge fuel gas to the outside of a fuel cell system along with water accumulated in the gas/liquid separation device. A change in pressure at a portion upstream of the discharge valve, which occurs due to an opening operation of the discharge valve, is detected or estimated, and an integral value is obtained by integrating the amount of change in the pressure with respect to time from when the discharge valve is opened or a parameter value corresponding to the integral value is obtained. The integral value represents an amount of fuel gas discharged due to the opening operation of the discharge valve. It is therefore possible to reliably discharge a desired amount of fuel gas by deciding a closing time at which the discharge valve is closed based on the integral value or the parameter value corresponding to the integral value.
