Abstract
A compressor arrangement for the operation of a fuel cell system, wherein a compressed air flow can be delivered from the compressor arrangement, which is driven by an electric motor, to the fuel cell system and wherein the compressor arrangement and optionally the electric motor are at least partly surrounded by a sound insulation, is characterized in that the sound insulation is permeable to air and is provided within a housing which at least partly surrounds the compressor and preferably also the electric motor, and in that at least a part of the air intake flow for the compressor arrangement can be directed through the air permeable sound insulation before it enters into the compressor inlet.
