Abstract: Hydrogen fuel cells air compressor is an important accessory of hydrogen fuel cell，but the high cost

caused by its high energy consumption hinders the further development of hydrogen fuel cell. In recent years，the

industry has gradually adopted variable frequency drives to control the operation of hydrogen fuel cell air

compressors，but currently the review of manufacturers and product parameters of variable frequency drives

dedicated to air compressors is lacking. It is not conducive to the standardization and maturity of the industry. In

order to give relevant researchers a reference，it is necessary to summarize the current status of the hydrogen fuel

cell air compressor. The advantages and principles of variable frequency drives to control air compressors，the

manufacturers and product parameters of dedicated variable frequency drives for air compressors at home and

abroad，and the technological difficulties and developing directions of using variable frequency drives technology

in hydrogen fuel cell air compressors were introduced.
