Various control schemes of power management for phosphoric acid fuel cell system

In this paper, the analysis of phosphoric acid fuel cell (PAFC) system is presented. Various control schemes of power management e.g. current, voltage, power, reactants flow pressure and temperature based control schemes are proposed with simple and easy to implement PI controller for PAFC operation. These control schemes can be utilized for power management purpose. The proposed model of PAFC along with these control schemes is realized in the MATLAB/Simulink environment. The performance of a PAFC system along with these proposed control schemes is found to be satisfactory even under dynamic conditions.
