Abstract

This paper focuses on proton exchange membrane fuel cells (PEMFCs) and their air supply system. The study investigates the application of advanced observers, specifically higher-order sliding mode observers with PI injection, to precisely estimate the partial pressure of oxygen in PEMFC air supply systems. These observers continuously monitor real-time system behavior and detect abnormal conditions, including faults such as sudden air manifold leaks. The primary objective of this research is to enhance the reliability, durability, and efficiency of PEMFCs by detecting faults in their air supply system, which is crucial for achieving optimal performance.
