Abstract
A structure of a fuel cell system and a controlling method thereof are provided. The structure of the fuel cell system includes a flow sensor that is configured to detect a flow of air introduced into the fuel cell system and an air compressor that is configured to compress the introduced air and has an air foil bearing to maintain minimum driving revolutions per minute or greater. Additionally, the system includes a flow adjuster that is connected to the fuel cell system. Accordingly, since an amount of air corresponding to a required amount of air of the fuel cell system is supplied by limiting or recirculating an excessive air supply while securing durability and durability of abrasion of the air compressor to which the air foil bearing is applied, a dry phenomenon of the fuel cell system including a stack due to the excessive supply of air is prevented.
