Enhancement of PEM Fuel Cell Performance with Direct Active Fuzzy Sliding Mode Controller
Improper reactant supply to the Proton Exchange Membrane Fuel Cell (PEMFC) and uncontrolled pressure across the fuel cell membrane are the serious issues which lead to a severe damage to the membrane and as a result reduced life time of the cell. By efficiently controlling these two issues the life time and performance of the fuel cell can be enhanced. This paper presents a Direct Active Fuzzy Sliding Mode Controller (DAFSMC) for PEMFC to control these parameters. The proposed DAFSMC controls the partial pressures of hydrogen and oxygen at the anode and cathode chambers respectively, by adjusting the rate of flow of the reactants supplied to the fuel cell. The DAFSMC has been developed and simulated in MATLAB-SIMULINK for various static and dynamic load conditions of the PEMFC to control the partial pressures of reactants and pressure difference across the membrane. The performance of DAFSMC has been compared with the other controllers such as conventional PI controller, Non-Linear Controller (NLC) and Sliding Mode Controller (SMC) which have been already reported in literature. The simulation results prove that the DAFSMC exhibits a better performance compared to the other referred controllers.
