US 2025/0092879 A1 · COMPRESSOR FOR A FUEL-CELL SYSTEM, AND FUEL-CELL SYSTEM HAVING SAME

Abstract

A compressor is for a fuel cell system, in particular a fuel cell system of a utility vehicle. The compressor includes a compressor housing, a compressor wheel, a rotationally driven compressor shaft which is operatively connected to the compressor wheel, and a bearing arrangement which supports the compressor shaft in the compressor housing so as to be rotatable about an axis of rotation, wherein the bearing arrangement includes an axial air bearing for absorbing axial forces between the compressor housing and the compressor shaft. The axial air bearing is a first axial air bearing, and the bearing arrangement also includes a second axial air bearing which is arranged at an axial spacing from the first axial air bearing and is additionally configured to absorb axial forces between the compressor housing and the compressor shaft.
