The invention relates to a side channel compressor (1) for a fuel cell system for conveying and/or compressing a gas, particularly hydrogen, comprising a housing (3) and a drive (6), wherein the housing (3) has a housing upper part (7) and a housing lower part (8), a compressor chamber (30) which is circulating in the housing (3) about an axis of rotation (4) and has at least one peripheral side channel (19), a compressor wheel (2) located in the housing (3), which is rotatably arranged about an axis of rotation (4) and is driven by the drive (6), said compressor wheel (2) comprising blades (5) arranged on the periphery thereof in the region of the compressor chamber (30), and comprising respectively a gas inlet opening (14) embodied on the housing (3) and a gas outlet opening (16) which are fluidically interconnected via the compressor chamber (30), in particular the at least one side channel (19). According to the invention, the drive (6) is designed as an axial field electric motor (6) which has a stator (12) and a rotor (10), wherein the stator (12) and the rotor (10) have a disc-shaped design and are formed so as to move about the axis of rotation (4), and wherein the stator (12) is arranged next to the rotor in the direction of the axis of rotation (4).
A side channel compressor (1) for a fuel cell system for conveying and/or compressing a gas, the side channel compressor (1) having a housing (3) and a drive (6), wherein the housing (3) has a housing upper portion (7) and a housing lower portion (8), having a compressor chamber (30) which extends in the housing (3) circumferentially around a rotation axis (4) and which has at least one circumferential side channel (19), having a compressor wheel which is located in the housing (3), which is arranged so as to be able to rotate about the rotation axis (4) and which is driven by the drive (6), wherein the compressor wheel (2) has on a circumference thereof blades (5) which are arranged in a region of the compressor chamber, and having in each case a gas inlet opening (14) and a gas outlet opening (16) which are formed in the housing (3) and which are connected to each other in fluid terms by the compressor chamber (30), characterized in that the drive (6) is an axial field electric motor (6), which has a stator (12) and a rotor (10),
A method for starting and/or switching off the side channel compressor (1), the side channel compressor (1) for a fuel cell system for conveying and/or compressing a gas, the side channel compressor (1) having a housing (3) and a drive (6), wherein the housing (3) has a housing upper portion (7) and a housing lower portion (8), having a compressor chamber (30) which extends in the housing (3) circumferentially around a rotation axis (4) and which has at least one circumferential side channel (19), having a compressor wheel which is located in the housing (3), which is arranged so as to be able to rotate about the rotation axis (4) and which is driven by the drive (6), wherein the compressor wheel (2) has on a circumference thereof blades (5) which are arranged in a region of the compressor chamber, and having in each case a gas inlet opening (14) and a gas outlet opening (16) which are formed in the housing (3) and which are connected to each other in fluid terms by the compressor chamber (30), characterized in that the drive (6) is an axial field electric motor (6), which has a stator (12) and a rotor (10),
