PURPOSE: A method for notifying an air filter exchange cycle in fuel cell vehicles is provided to prevent inefficient filter exchange through the determination of an accurate air filter changing time and to enhance fuel battery durability. CONSTITUTION: A method for notifying an air filter exchange cycle in fuel cell vehicles comprises the steps of: driving an air blower by classifying idle L1 rotation, intermediate power L2 rotation and high power L3 rotation; calculating air suction amount F1, F2, F3 in a driving state of L1, L2, L3 and calculating blower speed S1, S2, S3; repeating a logic loop and determining an air filter changing time through the load variation of the air blower represented by the relation of L1 and S1, L2 and S2, and L3 and S3. |
