Proton Exchange Membrane Fuel Cells

Large-scale commercialization of proton exchange membrane fuel cell (PEMFC) technology has been hindered by issues of reliability, and cost, which are related to the degradation of fuel cell performance. This book discusses the impacts of contamination and the contamination mitigation strategies to improve fuel cell performance and durability.

This book reviews issues and recent research progresses on proton exchange membrane fuel cells (PEMFCs) contamination, including contaminant sources, impacts of individual contaminant on the fuel cell performance, contamination mechanisms, modeling prediction of contamination effect, and contamination mitigation strategies. It provides a complete resource for understanding the contamination-related issues in the development of PEMFCs. The authors cover the impacts contaminants on PEMFC performance and the fundamental contamination mechanisms, the prediction of performance degradation and durability through modeling, and how to develop mitigation strategies.
