Efficiency and durability of proton exchange membrane fuel cell (PEMFC) are compromised by drying of the membrane and by water flooding. This paper introduces a novel water management strategy by exhaust gas recirculation (EGR). The PEM fuel cell system with cathode EGR has a simpler structure and operates at lower cost than the conventional one with an external humidifier. Based on a modified PEMFC system model with ERG description added, the water content characteristics are captured in the presence and abs…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
