Modeling and fuzzy based control of proton exchange membrane fuel cell

Clean and pollutant free energy can be produced from proton exchange membrane fuel cell which is a static power conversion device and can be installed at the point of use eliminating the transmission and distribution losses. The ability to maintain constant voltage by the PEM fuel cell can be achieved by using a Fuzzy Logic controller. The designing of controller is made easy after observing the response of the fuel cell for changes in temperature and pressure of input reactant gas by dynamically modeling the fuel cell. The dynamic model is implemented in MATLAB and simulation results of Fuzzy controlled system confirm improved voltage regulation of the proposed system.
