Analysis and control of a fuel delivery system considering a two-phase anode model of the polymer electrolyte membrane fuel cell stack

► We modeled a fuel delivery system (FDS) using both an ejector and a blower as recirculation pumps. ► We proposed a dynamic model of half a cell (anodic part) for the controller design and system simulation considering the liquid water effect. ► The state feedback controller is designed based on the linearization of FDS and tested under different load modes. ► A dynamic purging control based on the load change is presented and tested by the model simulation of the controllers and FDS.
