摘要： PURPOSE: To prevent the collision energy absorption member of an electric vehicle from being hindered from absorbing collision energy by forming a collision deformation acceleration section thereon, and mounting a fuel cell on the member, so as to keep a formation plane along a fuel cell stack direction faced to the acceleration section. CONSTITUTION: A frame side member 14 provided at both sides of the front section 12 of an electric vehicle 10 is provided with an energy absorbing section 14a for absorbing collision energy via substantial deformation at the time of collision, and a cutout section 16 is formed on the intermediate lower side of the section 14a for allowing the upward flexure thereof. Also, a fuel cell 20 contained in a housing case 30 is mounted on the section 14a. In this case, a notch section 32 with a rectangular upper side and both sides open in a wedge form is formed on the center of the case 30, and a groove 34 connecting straight the end of the section 32 is formed on the bottom center of the case 30. In addition, the fuel cell 20 is mounted, so as to keep the groove 34 and the cutout section 16 aligned with each other.

摘要： PURPOSE:To prevent exhaust property from deteriorating when an engine is cold with the engine equipped with a means for feedback controlling air-fuel ratio to be brought to a target air-fuel ratio as well as feeding fuel according to operating conditions by making the air-fuel ratio leaner when engine temperatures are at or below a specified value. CONSTITUTION:An electronic control device 30 feeds fuel based on detected values from an intake pipe pressure sensor 21, an intake temperature sensor 22, a throttle opening sensor 23, a revolution angle sensor 26, an oxygen sensor 25, etc. as well as on operating conditions to perform feedback control for a target air-fuel ratio. Also, the electronic control device 30, based on detected values from a water temperature sensor 24, increases a skip constant and an integral constant when controlling the air-fuel ratio to leaner side when the water temperature is for instance at 70 deg.C or lower. Or the device 30 controls so that a delay time is extended when starting control of the air-fuel ratio to richer side so that the air-fuel ratio is brought to leaner side.

摘要： PROBLEM TO BE SOLVED: To avoid degradation and damage of a fuel cell system caused by starting at the time of freezing.
SOLUTION: A shutoff valve 21 is opened when a starting operation of the fuel cell system is carried out, and a temperature sensor 102 measures temperature of the open air. If the measured temperature is a designated value or below, a pressure sensor 54 determines whether or not the pressure value is normal. If it is normal, a discharge valve 26 is opened, and the pressure sensor 54 determines whether or not an amount of measured pressure reduction is normal. Then, the discharge valve is closed, the pressure sensor 54 determines whether or not an amount of measured pressure increase is normal. A hydrogen pump 45 is started, and it is determined whether or not the number of rotation of the hydrogen pump is normal. A compressor 41 is operated, and determines whether a pressure value measured by a pressure sensor 53 is normal or not. If there is any abnormality in any of the determined results, it is determined that there exist some frozen components, and starting of a fuel cell system is inhibited.

摘要： PROBLEM TO BE SOLVED: To timely output required power when starting feeding in a fuel cell system.
SOLUTION: In the fuel cell system FC, a compressor 41 and a low-pressure valve 24 are temporarily driven for supplying air and hydrogen to a fuel cell stack even in an intermittent operation mode. When the air is supplied, voltage drop in the stop of the system can be suppressed by keeping a fixed amount of air remaining in an air supply system. When hydrogen is supplied, hydrogen permeated to the air supply system is replenished, and the supply delay of hydrogen can be suppressed. Additionally, a signal is inputted from a brake sensor 102, a shift selector 104, or the like and the air and hydrogen are supplied in advance by estimating that a vehicle mounting the fuel cell system FC is accelerated. With such a configuration, delay in power generation occurring when activating and reactivating the fuel cell system FC can be canceled.

摘要： PROBLEM TO BE SOLVED: To suppress shortened life caused by operation when increasing an impurity concentration in an anode in a fuel cell system.
SOLUTION: The difference between a stack temperature and an outside air temperature when stopping the operation of a fuel cell and that between the stack temperature and the outside air temperature when activating the operation of the fuel cell are obtained and temperature ratio is defined as "temperature difference in activation/that in stop." According the temperature ratio, lapse time from when stopping the operation of the fuel cell and the concentration of nitrogen permeating an electrolyte film from a cathode to an anode are estimated. Additionally, corresponding to the estimated value of the nitrogen concentration, the output value of the fuel cell stack is restricted, thus suppressing excessive power generation while the impurity concentration of the anode is high.

摘要： PROBLEM TO BE SOLVED: To equally distribute fuel or the like to each stack, facilitate mounting, and miniaturize a fuel cell which is equipped with a plurality of stacks. SOLUTION: The fuel cell 10 is composed of stacks 12A-12D in which a supply and exhaust passage is formed in the stacking direction; a supply and exhaust member 40 of fuel or the like interposed between the stacks 12A-12D and supplying exhausting fuel or the like to and from the the stacks 12A-12D from the interposed surface; an upper case 80 and a lower case 90 forming a housing container of the stacks 12A-12D; and a pressing mechanism 110 applying pressure in the stacking direction to the stacks 12A-12D. The supply and exhaust passages to and from the stacks 12A-12D are formed in a similar shape. As a result, fuel or the like can equally be distributed in the stacks 12A-12D. Since the fuel cell is assembled only by connecting the supply and exhaust member of fuel or the like with a fuel supply and exhaust device or the like, mounting is facilitated, and the fuel cell is miniaturized.

摘要： PURPOSE:To improve the sealing ability by providing a groove portion on the outer periphery of an insulator or forming the inner periphery like a projected surface. CONSTITUTION:An insulator 88 is installed on an annular groove 86 of the outer periphery of an injector. The insulator 88 has a gap (w) to the opposed inner surface of an injector install hole and a groove 99 having a V-shaped section on the outer periphery thereof, so that the insulator is made flexible by the groove 99 and in the case of installing the injector 17 with a gradient, the insulator follows it to be deformed. Thus, sealing is ensured. The insulator 88 has a projected surface 101 in the inner periphery and is brought into close contact with the bottom surface 86A of the seal install groove 86 so that sealing is also accomplished in this portion.
