Abstract:

The control of the compressor in fuel cell systems (FCS) plays a crucial role in ensuring stable and efficient operation. To further enhance the efficiency and durability of FCS, considering the impact of power allocation on the air supply control of the system, this work analyzes the coupling relationship between the control variables of the compressor, the state of the air supply system in fuel cells, and the output of the FCS. A coordinated control model for fuel cell hybrid electric vehicle (FCHEV) considering the compressor is reconstructed. A system coordination control strategy based on a cascade feedback structure is proposed, and simulation and experimental verification of system performance are conducted under different reference values of Oxygen Excess Ratio (OER).

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.
