Abstract
A method of controlling a cooling fan can maximize available stack power through optimal duty control of the cooling fan by considering deterioration of a fuel cell stack. The method includes determining whether a duty map update condition is satisfied based on a state variable for cooling fan control; when the duty map update condition is satisfied, determining available power of a fuel cell stack for each cooling water temperature corresponding to a current fuel cell stack deterioration using a detected cooling water temperature; determining a target cooling water temperature at which available power of the fuel cell stack is maximized from the determined available power of the fuel cell stack for each cooling water temperature; and then updating a cooling fan duty map using the determined target cooling water temperature.
