Multiple-Fuel Cell Module Architecture Investigation: A Key to High Efficiency in Heavy-Duty Electric Transportation

International audienceThis article is on the subject of the multiple-fuel cell (MFC)power module system in heavy-duty (HD) electric transportation. TheMFC system is promising for increasing the system power level,redundancy, and lifetime and to reduce costs. In particular, thenumber of FC modules can affect system fluidic and electricalarchitectures significantly. Furthermore, system complexity andperformance can also be influenced. Different MFC system electricarchitectures can lead to system global efficiency varying a lot,which is closely related to fuel economy. Meanwhile, anoptimization strategy can also be used to help assign power demandamong FC modules more efficiently, then help reduce power loss andhydrogen consumption. Hence, this article aims to make aninvestigation of MFC system architecture development in HD electrictransportation and find the most suitable architecture from theview of efficiency and fuel economy based on quantitative analysis
