An Air Supply Strategy with Turbocharging for Fuel Cells

An air supply strategy based on a centrifugal compressor with turbocharging for Unmanned Aerial Vehicle (UAV) fuel cells is proposed in this paper. The turbocharging is used to recover the energy of the exhausted gas from the fuel cell cathode. The mathematical model of the system is established and analyzed. And the air supply control method is proposed to satisfy the requirement of the fuel cell stack. The validation of the proposed strategy is verified by simulation. The simulation results show that the proposed strategy improves the efficiency of the fuel cell system by 7.8%.
