Fault analysis and diagnosis of Solid Oxide Fuel Cell System

摘要

In order to extend the life of the Solid Oxide Fuel Cell system and maximize the performance of the stack, it is very important to study the fault diagnosis method of SOFC system. At First, this paper analyzes the phenomenon and mechanism of the blower fault and leakage fault for the SOFC system. At last, this paper introduce a method which uses the fault tree method to diagnose the external system fault (blower mechanical fault and the reformer leakage fault) for ensuring the system safe and preventing further escalation of the fault.
