    • A silencer installed in a fuel cell system includes a plurality of expansion chambers connected to a predetermined apparatus of the fuel cell system, wherein the plurality of expansion chambers serially reduces acoustic noise of air discharged from the predetermined apparatus and a resonator connected to an expansion chamber of the plurality of expansion chambers, wherein the resonator reduces acoustic noise received from the expansion chamber in another frequency band, which is different from a frequency band of the acoustic noise reduced by the plurality of expansion chambers, where one of the plurality of expansion chambers comprises an inlet pipe which receives air from the predetermined apparatus, another of the plurality of expansion chambers comprises an outlet pipe which discharges air flowed into the plurality of expansion chambers, and an intermediate pipe is disposed between the plurality of expansion chambers.
    • 安装在燃料电池系统中的消声器包括连接到燃料电池系统的预定装置的多个膨胀室,其中多个膨胀室串联地减少从预定装置排放的空气的声学噪声和连接到膨胀室的谐振器 的多个膨胀室中的一个,其中所述谐振器减小在另一频带中从所述膨胀室接收的声学噪声,所述另一频带不同于由所述多个膨胀室减小的声学噪声的频带,其中所述多个膨胀室 包括从所述预定装置接收空气的入口管,所述多个膨胀室中的另一个包括排出流入所述多个膨胀室的空气的出口管,并且在所述多个膨胀室之间设置中间管。
