Interactions between fuel cell and DC/DC converter for fuel cell electric vehicle applications: Influence of faults

Over the last few decades, the proton exchange membrane fuel cell (PEMFC) has been named by public and private researchers as excellent candidate for automotive applications with a high degree of autonomy and zero pollutant emissions (gases, noise). However, before the commercialization of fuel cell electric vehicles (FCEV), some challenging issues remain to be solved, especially the reliability of power trains in case of faults. In this perspective, the purpose of this paper is to study the influence of faults on the interactions between fuel cell and DC/DC converter. The main contribution of this work is to study different faults which could occur during the operation both for FC and DC/DC converter.
