Abstract

Recycling pipeline for fuel cell stacks of recirculation rate low, put forward the hydrogen supply system for fuel cell cycle control scheme, according to the amount of gas recirculation in the recirculating pipeline accurately estimated by purging purge valve of hydrogen concentration, through the feedback of each gas purging, adjust the opening of the purge valve, improve utilization rate of hydrogen, and has carried on the simulation analysis to the scheme. The simulation results show that the utilization rate of hydrogen on the anode side of fuel cell is significantly improved, up to 92.733%, and the durability of fuel cell stack is improved.
