A stable air supply system in a fuel cell system produces heat and electricity by combining hydrogen modified from a major raw material selected from various hydrogen compounds, with oxygen existing in air. An air supply device and an air supply method in a fuel cell system, automate a lamda control, and achieve a fuel cell system operation efficiently and stably coping with pressure loss and pulsation occurring within the system, while using a minimum number of balance-of-plant (BOP) units. A method efficiently and precisely supplies air during the start-up and operation of the fuel cell system, while preventing flame failure of a burner and maintaining an appropriate carbon monoxide concentration even when an abrupt flow rate variation occurs. In this regard, an operating method is economical and stable in terms of the costs and configuration of the fuel cell system. |
