The invention relates to a method for controlling an air feeder of an automobile fuel battery. The air feeder comprises an air feeding controller, a global positioning system (GPS)/global information system (GIS) interface, a remote detector, a flow meter and an air compressor, the air feeding controller real-timely acquires information of road surface types, average automobile speeds, average gradient and the like of road sections where an automobile travels through the GPS/GIS interface, an automobile speed sensor measures and real-timely collects speeds of the automobile , the remote detector real-timely collects speeds of a front automobile, expected automobile speed at the next moment of the automobile is obtained by means of weighted average, expected power at the next moment is calculated out according to the expected automobile speeds and the average gradient, accordingly, expected air supply quantity is calculated out, actual air flow is fast identical to expected air flow by means of optimized control, influence of dynamic response time lag of the air compressor is eliminated, oxygen starvation is avoided, prediction control of air supply is achieved, power supply efficiencies of the fuel battery are improved, and service life of the fuel battery is prolonged.
