Analysis of Influencing Factors on Dynamic Performance of PEMFC Air Supply System

Air supply system is one of the most important auxiliary subsystems of proton exchange membrane fuel cell (PEMFC). The response speed of voltage and current in fuel cell system greatly depends on the dynamic performance of air supply system. In this paper, based on AMESim software
^®
, a fuel cell air supply system model of 72kW stack is built. The influence of air compressor response speed, buffer tank and flow resistance on the dynamic response characteristics of air supply system is analyzed, and the influence mechanism is briefly analyzed according to the simulation results.
