摘要： A method of shutting down a fuel cell system includes a first step of supplying hydrogen gas and air to a fuel cell stack to thereby cause the fuel cell stack to generate electricity, and a second step of stopping supply of the hydrogen gas, and then supplying air to the fuel cell stack so as to cause the fuel cell stack to generate electricity upon detection of a command to shut down the fuel cell stack. In the second step, when the pressure of the hydrogen gas is lowered to a preset lower-limit value based on an anode pressure, which actually is measured, the fuel cell stack is caused to stop generating electricity.

摘要： A fuel cell system includes a replacing unit for replacing a gas remaining in the anode of the fuel cell with the anode gas supplied anew by the anode gas supply unit when starting up the fuel cell. The amount of the anode gas is set to be lower, if the operation condition determining unit determines that the last operation was performed in a low-temperature and short-time operation mode. The operation condition determining unit sets the amount of the anode gas so that the gas remaining in the anode can be replaced with the anode gas with an entire anode capacity if the anode was been scavenged while no electro-chemical reaction was progressing in the fuel cell. The present invention can set the amount of anode gas appropriately when starting up the fuel cell.

摘要： A fuel cell system includes a fuel cell in which a first reactant gas and a second reactant gas are supplied to generate electricity. An evaporator evaporates a raw fuel, which combustor exhaust gas discharged from the fuel cell and uses the exhaust gas to evaporate and volatile a raw material for the first reactant gas. A reformer reforms the evaporated and volatilized raw fuel vapor of the raw material by a reforming catalyst to produce the first reactant gas. An air-introducing device introduces the air that is used to be reformed into the evaporator or the reformed in a manner wherein the flow rate of the air is controlled depending upon the output from the fuel cell and upon the temperature of the raw fuel vapor.

摘要： A simulation apparatus and an information storage medium are described which can perform collision decision for a moving object with respect to another displayed object with a reduced the amount of data and the computation load. There are included a decision region defining section (114) which defines a decision region which specifies a three-dimensional space for collision decision based on the entire shape of a target object to be collided or of a portion thereof, and a collision decision section (118) which decides whether a collision has occurred or not, based on whether or non the position of the moving object is located within the decision region. When the decision region defining section (114) defines a negative hit region which specifies a noncollision region as the decision region, and the collision decision section (118) decides that no collision has occurred if the position of the moving object is located within the negative hit region. Further, when the decision region defining section (114) defines a combination of the negative hit region and a positive hit region which specifies a collision region as the decision region, with these hit regions at least partly overlapping one another, then the collision decision section (118) decides whether a collision has occurred or not based on given rules if the position of the moving object is located within the overlapping region.

摘要： In a dissimilar material joint structure that joins together an anti vibration bar (first member) 14 and a end cap (second member) 15, which is a dissimilar metal material to the anti vibration bar 14, the anti vibration bar 14 is sandwiched by a plurality of end caps (second members) 151 and 152, and these respective end caps 151 and 152 are joined together by welding. Due to contraction of a weld material 153 welding the end caps 151 and 152, the anti vibration bar 14 is sandwiched between the end caps 151 and 152, whereby the anti vibration bar 14 and the end cap 15 are joined. Consequently, a thermal treatment for welding dissimilar metal materials is not required, and the welding operation can be carried out easily.
