- the oxidizing gas discharge line 14 is provided with a silencer 20 surrounded by a broken line in FIG. As will be described later, the muffling unit 20 is configured so that the muffling ability can be varied in accordance with the traveling state of the fuel cell vehicle 1. Although not shown, the oxidizing gas discharge line 14 on the upstream side of the silencer 20 is provided with a pressure regulating valve that adjusts the pressure of the oxidizing gas in the fuel cell 4, and downstream of the pressure regulating valve. The fuel gas discharge line 1 and 2 are connected.
- the muffler 20 includes a muffler 21 for introducing a mixed gas of oxidizing off gas and hydrogen off gas to mute, a main flow path 2 2 in which the muffler 21 is interposed, and a main flow path 2 2 in parallel.

- the upstream end of the bypass passage 23 is connected to the exhaust port of the directional control valve 24, and the downstream end is connected to the downstream side of the silencer 21 in the main passage 22.
- the bypass passage 23 is composed of a pipe having a smaller or equivalent inner diameter than that of the main flow passage 22.
- the bypass passages 2 and 3 are not provided with auxiliary equipment (for example, a filter) having a silencing action. For this reason, the mixed gas passing through the bypass passage 23 is exhausted from the downstream side of the main passage 22 to the outside without being silenced.
- the directional control valve 24 (switching means) is composed of a three-way valve, and the supply port is connected to the main flow path 22 on the fuel cell 4 side.

- the silencing capability of the silencing unit 20 is mechanically changed according to the traveling state. Therefore, if the sound deadening capacity of the sound deadening section 20 increases due to high speed running, it is possible to prevent the generation of noise more than necessary. Also, if the noise reduction capability of the noise reduction unit 20 decreases due to low speed running, an air flow noise corresponding to the flow rate of the mixed gas is generated. As a result, when driving at low speeds, other fuel vehicles such as pedestrians and bicycles

As a result, it is not necessary to separately provide a pseudo sound generator as in the prior art, which can simplify the structure and generate an operation sound with less sense of incongruity.
- the silencer 20 is provided in the oxidizing gas discharge line 14, but the silencer 20 can also be provided in the oxidizing gas supply line 13. However, Considering the influence of the pressure loss of the oxidizing gas pumped to the fuel cell 4 by the compressor 17, it is preferable to provide the silencer 20 on the downstream side of the fuel cell 4 as in this embodiment.
- the fuel gas discharge line 12 is connected to the oxidizing gas discharge line 14 on the upstream side of the silencer 20, it is of course not limited to this position.

Further, the directional control valve 24 may be configured as a valve capable of applying pressure, and the directional control valve 24 may be configured to mechanically perform the switching operation by applying a predetermined pressure. . For example, the pressure of the oxidizing gas in the oxidizing gas supply line 1 3, the pressure of the oxidizing off gas in the oxidizing gas discharge line 1 4, the pressure of the hydrogen gas in the fuel gas supplying line 1 1, or the hydrogen in the fuel gas discharging line 1 2 The off-gas pressure may be applied to the directional control valve 24.
