I. Introduction
Proton exchange membrane fuel cells (PEMFCs) are efficient in hydrogen utilization, which offering high energy conversion efficiency, low noise, zero carbon emissions, low operating temperatures, and good start-stop performance, making them promising in the field of hydrogen energy utilization [1]–[3]. To ensure the efficient and stable operation of FCS, the air supply system, consisting of compressors, air filters, humidifiers, and coolers, needs to provide the fuel cell with adequate air flow rate, and pressure [4], [5]. However, the unreasonable system power distribution and compressor's flow rate output may decrease the durability and efficiency of FCS. Thus, a cascade coordinated feedback control for fuel cell air supply system, which takes power distribution into consideration, is imperative.
