This paper proposes a Lead-Lag optimal controller in order to control of one of the most important types of fuel cell, namely proton exchange membrane fuel cell (PEMFC). At first, the introducing and implementation of the PEMFC is present and next, during system load variations the proposed controller is designed. The controller should be designed against the load variations for keeping in a fixed value of fuel cell output voltage. Here, the Lead-Lag Controller is used which its coefficients are optimized based on Honey Bee Mating Optimization (HBMO). In order to use this algorithm, at first, the problem is written as an optimization problem which includes the objective function and constraints, and then to achieve the most desirable controller, HBMO algorithm is applied to solve the problem. Simulation results are done for various loads in time domain, and the results show the efficiency of the proposed controller in contrast to the previous controllers.

Key words: Lead-Lag controller, proton exchange membrane fuel cell (PEMFC), Honey Bee Mating Optimization (HBMO), fuel cell output voltage.
