Conventional and advanced exergy analyses of a vehicular proton exchange membrane fuel cell power system

Vehicles powered by proton exchange membrane fuel cell have received lots of attention due to various merits. A comprehensive power system with parallel-arranged heat recovery strategy for reactants preheating is proposed and investigated. Thermodynamic model the established validated rigorously. In order minimize total exergy destruction, an acceptable interval stream separation ratio exchangers in this varies from 0.01-0.90. Conventional advanced analyses are presented. Real improvement potential quantified: 46.42% destruction avoidable, priority orders given: PEMFC stack >WP>AC>R>CHE>AHE>HC. It found that a strong interaction exists since 84% exogenous. Interactions each component remaining components analyzed. 87.97% exogenous, which indicates auxiliary will be effective improve system. This paper could provide directions further on efficiency deeper understandings interactions between components.
