A Review of Multi-Stack PEM Fuel Cell Systems: Advantages, Challenges and On-Going Applications in the Industrial Market

The purpose of this paper is to provide a conceptual framework of the Multi-stack Proton exchange membrane Fuel cell technology (PEMFC) system state of the art. Recent developments in the fuel cell (FC) researches have increased the need of raising the system reliability, its life time and its efficiency. The electrical configuration of a multi-stack FC system, the power sharing and the hybridization rate are the main topics in this paper. There was a significant positive correlation between increasing the Multi-Stack Fuel Cell's (MSFC) system application in the industry especially in the transportation sector, and the decreasing of the current environmental pollution crisis. Keywords- Multi-stack Fuel Cell system; PEMFC; Energy management; Redundancy; Electrical Architecture.
