摘要:
To provide the fuel cell system, which can prevents the imperfect combustion of the fuel gas in combustor caused by shortage of the air exhausted from the fuel cell so that the harmful components is not contained in the exhausted gas, and can prevents the decreasing of the cell voltage by enabling drainage of the produced water from fuel cell certainly. A flow rate controller 8 is provided in the position between the air compressor 4 and the fuel cell 1 of the air supply line 6. The control unit CU is connected to the air supply line 6, and set the openings of the flow rate controller 8 as temporally wide, and a flow rate of the air supplied to the fuel cell is increased for a predetermined period of time. Then, set the opening of the flow rate controller 8 as gradually narrow, and the flow rate of the air supplied to the fuel cell is decreased gradually.

A reaction gas supply apparatus for a fuel cell is able to adapt to various kinds of operating states, and can provide improved responsiveness with respect to a required output. The apparatus has: a compressor 2 that supplies pressurized air to a cathode electrode of a fuel cell 1; a hydrogen supply device 30 that supplies hydrogen to an anode electrode of the fuel cell 1; a control device 10 that regulates the pressure of the cathode electrode by controlling the compressor 2 according to an operating state of the fuel cell 1; and a regulator 5 that is applied with the air pressure of the cathode electrode as a reference pressure, and regulates the supply pressure to the anode electrode based on this air pressure. Moreover there is provided a pressure regulator 39 that is capable of regulating the reference pressure that is applied to the regulator 5, by discharging air from an air flow passage for the air pressure that is applied to the regulator 5.

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.

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.
