Abstract
A control method for a fuel cell stop mode is provided. The method includes measuring an air flow rate supplied to a fuel cell stack and when a fuel cell stop mode is entered, determining an oxygen distribution state between cells included in the fuel cell stack based on the measured air flow rate. Air supply is then supplied to the fuel cell stack or the air supply to the fuel cell stack is interrupted based on the determined oxygen distribution state.
