[the 1st embodiment]
As shown in Figure 1, fuel cell powered vehicle 1 is equipped with fuel cell system 3 on car body 2.The fuel cell 4 of fuel cell system 3 is connected via not shown inverter and not shown drive motor, and drive motor makes not shown axletree rotation.This fuel-cell vehicle is not limited only to the fuel cell powered vehicle 1 of four-wheel shown in Figure 1, also can be the two-wheel automobile, also can be electric train, bicycle etc. in addition.
Fuel cell 4 is the battery pack structure that a plurality of cells (single lattice battery) are stacked.Fuel cell 4, thus accept to produce electric power (propelling energy) as the air of oxidizing gas and the supply of the hydrogen of the gas that acts as a fuel.The battery 4 that acts as a fuel has various kinds such as phosphatic type, but here is made of solid macromolecular electrolyte type.Method as hydrogen being offered fuel cell 4 can adopt the method that crude fuels such as natural fuels is modified as hydrogen on car body 2, perhaps also can adopt the method that the bomb that stores hydrogen is installed on car body 2.
On the gas pipe line 5 of fuel cell system 3, be provided with: the fuel gas supply pipeline 11 that is used for providing to fuel cell 4 via pressure regulating valve hydrogen from for example bomb, be used for discharging the fuel gas downstream line 12 of hydrogen exhaust from fuel cell 4, be used for the oxidizing gas supply line 13 of oxidizing gas being provided and being used for discharging the oxidizing gas downstream line 14 of oxidizing gas exhausts from fuel cell 4 to fuel cell 4.Fuel gas downstream line 12 and oxidizing gas downstream line 14 interflow, finally discharge to the outside of car body 2 at hydrogen exhaust and oxidizing gas exhaust interflow.
On oxidizing gas supply line 13, be provided with compressor 17 (pressure device) to fuel cell 4 positive delivery oxidizing gases.Compressor 17 sucks air and pressurization in the atmosphere, and provides air as oxidizing gas via not shown humidifier to fuel cell 4.By the rotating speed of motor of control, adjust flow to the oxidizing gas of fuel cell 4 positive delivery as the drive source of compressor 17.In the time of running at high speed of fuel cell powered vehicle 1 etc., fuel cell 4 is under the higher load condition, and oxidizing gas also becomes big flow.On the other hand, in the time of low speed driving of fuel cell powered vehicle 1 etc., fuel cell 4 is under the low load condition, and oxidizing gas also becomes low discharge.
On oxidizing gas downstream line 14, be provided with the noise elimination portion 20 that with dashed lines is surrounded in Fig. 1.As described later, noise elimination portion 20 constitute can fuel cell automobile 1 travel conditions change its acoustical absorptivity.In addition,, on the oxidizing gas downstream line 14 of the upstream side of noise elimination portion 20, be provided with the pressure regulating valve of the pressure of adjusting the oxidizing gas in the fuel cell 4, be connected with fuel gas downstream line 12 in the downstream of pressure regulating valve though diagram is omitted.
Thereby noise silencer 21 can be by for example making the intumescent noise silencer of miscellaneous gas expansion performance noise elimination effect or by the inside at noise silencer 21 thereby the counter-rotative type noise silencer of miscellaneous gas counter-rotating performance noise elimination effect is constituted by the inside at noise silencer 21.The inside of noise silencer 21 constitutes sound absorption materialss such as can setting glass fibre.The noise silencer 21 of present embodiment constitutes the oxidizing gas exhaust in the time of mainly can carrying out big flow or the noise elimination of miscellaneous gas.In addition, noise silencer 21 also can be can direct mount in the exhausr port of primary air path 22 sides of directional control valve 24.
Bypass path 23, its upstream extremity are connected on the exhausr port of directional control valve 24, and downstream end is connected the downstream of the noise silencer 21 of primary air path 22.Bypass path 23 is made of than primary air path 22 little or equal pipes internal diameter.On bypass path 23, there is not to be provided with auxiliary engine with noise elimination effect (for example filter etc.).Therefore, do not accept the noise elimination effect by the miscellaneous gas after the bypass path 23 and directly discharge to the outside from the downstream of primary air path 22.
Directional control valve 24 (switch unit) is made of triple valve, and supply port is connected on the primary air path 22 of fuel cell 4 sides.Directional control valve 24 constitutes, and the flow velocity based on flowing through gas (being miscellaneous gas) herein mechanically carries out change action.
Specifically, when miscellaneous gas became the travel conditions of running at high speed of fuel cell powered vehicle 1 of big flow, the flow velocity of miscellaneous gas also became at a high speed.When miscellaneous gas became high flow rate, directional control valve 24 mechanically carried out change action to noise silencer 21 sides.Thus, miscellaneous gas is eliminated the noise and is discharged to the outside then by noise silencer 21.That is, when the travel conditions of running at high speed, the acoustical absorptivity of noise elimination portion 20 rises overally.
On the other hand, when miscellaneous gas became the travel conditions of low speed driving of fuel cell powered vehicle 1 of low discharge, the flow velocity of miscellaneous gas also became low speed.When miscellaneous gas became low flow velocity, directional control valve 24 mechanically carried out change action to bypass path 23 sides.Thus, miscellaneous gas does not pass through bypass path 23 and discharges to the outside by noise silencer 21.That is, because miscellaneous gas is not in 20 noise eliminations of noise elimination portion, so when the travel conditions of low speed driving, the acoustical absorptivity of noise elimination portion 20 is whole to descend, and is essentially 0.
As mentioned above, according to the fuel cell powered vehicle 1 of present embodiment, the acoustical absorptivity of noise elimination portion 20 and its travel conditions mechanically change accordingly.Therefore, thus when the acoustical absorptivity that becomes the noise elimination portion 20 that runs at high speed rises, can prevent to produce necessary above noise.In addition, thereby when the acoustical absorptivity that becomes low speed driving noise elimination portion 20 descends, the corresponding air-flow sound of flow velocity of generation and miscellaneous gas.Thus, when low speed driving, other vehicle such as pedestrian, bicycle, can be by action sound identification fuel cell powered vehicle 1 approaching.
That is, if different with present embodiment, also miscellaneous gas is imported noise silencer 21 when low speed driving, then air-flow sound (exhaust sound) is fully eliminated the noise, thereby is difficult to discern the approaching of fuel cell powered vehicle 1.Relative therewith, shown in present embodiment, owing to when low speed driving, do not make miscellaneous gas pass through noise silencer 21, so though just relatively but still can increase exhaust sound.Therefore, when low speed driving, approaching for fuel cell powered vehicle 1 can be aroused pedestrian's etc. attention suitably.
Like this, according to present embodiment, even the general quiet fuel cell powered vehicle 1 of ratio engine vehicle ' sound, by effectively utilizing the noise elimination portion 20 of oxidizing gas downstream line 14, change its acoustical absorptivity according to travel conditions, also can produce and the corresponding sound of travel conditions.Thus, do not have to be provided with in addition necessity of such in the past simulation tone generating device etc., can produce inharmonious less action sound simultaneously in textural simplification.
In addition, in the present embodiment, noise elimination portion 20 has been located on the oxidizing gas downstream line 14, but also noise elimination portion 20 can be located on the oxidizing gas supply line 13.But, preferably as present embodiment, noise elimination portion 20 is located at the downstream of fuel cell 4 if consider by the influence of compressor 17 to the loss of pressure of the oxidizing gas of fuel cell 4 positive delivery.
In addition, fuel gas downstream line 12 is connected on the oxidizing gas downstream line 14 of upstream side of noise elimination portion 20, but is not limited to this position certainly.For example, its connection location also can be the downstream of noise elimination portion 20, also can be the primary air path 22 between directional control valve 24 and the noise silencer 21.In the latter case, directional control valve 24 is not based on the flow velocity of miscellaneous gas, and the flow velocity that is based on the oxidizing gas exhaust carries out change action.
In addition, the directional control valve 24 that works as switch unit is not limited to the flow velocity of gas, also can constitute the pressure of gas, flow etc. as the setting key element that is used for change action.In addition, also can constitute directional control valve 24, thereby directional control valve 24 can constitute by additional predetermined pressure and mechanically carries out change action by valve that can additonal pressure.For example also can on directional control valve 24, act on the pressure of the hydrogen exhaust of the pressure of hydrogen of pressure, fuel gas supply pipeline 11 of oxidizing gas exhaust of pressure, oxidizing gas downstream line 14 of the oxidizing gas of oxidizing gas supply line 13 or fuel gas downstream line 12.
In addition, directional control valve 24 can be the structure that switches to any side of noise silencer 21 sides and bypass path 23 sides fully, and the flow that also can be used as the miscellaneous gas that will discharge is distributed to the distributing box of noise silencer 21 sides and bypass path 23 sides with specified amount respectively and constituted.For example, distributing box can be when low speed driving imports the flow of miscellaneous gas to bypass path 23 sides than noise silencer 21 sides more, on the other hand, imports the flow of miscellaneous gas than bypass path 23 sides to noise silencer 21 sides when running at high speed more.
