To compete with internal combustion engines fuel cell system must operate and function at least as well as conventional engines. The fuel cell system power properties depends on the air and hydrogen feed, flow and pressure regulation, and heat and water management. Choosing an airflow control method is very important decision that defines many characteristics of the fuel cell system. The air supply method of the cathode side of the fuel cell can contribute to improvement of the system performance. A fuel cell is a stochastic object. Application gradient extremum control provides to automatical adjusting the parameters of a controller to actual characteristics of an object. In this paper was described airflow control of the fuel cell system in order to determine and hold the maximal value of net power produced by the fuel cell stack, regardless of changes of the parameters of the object of control and its outer environment. The presented control algorithm can be used for other types of fuel cells systems of both high and low power.
