Fault Tree Analysis of Degradation Mechanisms in a Low-Temperature PEMFC System under Two Different Anode Circulation Modes
This study investigates the impact of hydrogen supply subsystem configurations on the durability of Low Temperature Proton Exchange Membrane Fuel Cells in vehicles. Four configurations are analyzed: flow-through, dead-end anode, recirculation with pump, and with ejector. Using Fault Tree Analysis, the paper identifies degradation pathways leading to potential failures in two configurations: dead-end anode and hydrogen recirculation. Nitrogen and water accumulation at the anode is a key focus, with the aim of assessing their impact on membrane and anode compartment degradation. While these configurations improve hydrogen utilization, they also introduce risks that may reduce fuel cell system lifetime
