To realize the commercialization of proton exchange membrane (PEM) fuel cells, durability and reliability remain big challenges. This paper aims to develop a fault detection, identification and analysis methodology based on a commercial fuel cell system. Effect of air stoichiometry is studied using electrochemical impedance spectroscopy (EIS). Relevant faults are: oxygen starvation, water flooding...
Finding the location of a fault in code is an important research and practical problem, which often requires much time and manual effort. To automate this time consuming task, a class of predicate-based statistical fault localization techniques have been proposed, which test the similarity of dynamic predicate spectra between non-failed runs and failed runs and suggest suspicious predicates to the...
