PROBLEM TO BE SOLVED: To achieve damping of sound by suppressing generation of heat. SOLUTION: In the compressor structure 10 for operating the fuel cell system 22, the flow 20 of the compressed air is distributed from the compressor structure 10 which is driven by an electric motor 14 to the fuel cell system 22, and the compressor structure 10 and the electric motor 14 as an option are surrounded at least partially by a sound insulating means 32. In this compressor structure 10, the sound insulation means 32 transmits air and the compressor structure 10 and preferably the electric motor 14 are provided in the housing 30 surrounding them. At least part of the air suction flow 18 for the compressor structure is enabled to be guided to pass the sound insulation means 32 before it enters the compressor entrance 38. |
