Ejector performance influence on a solid oxide fuel cell anodic recirculation system

This work deals with the design and off-design performance evaluation of an anodic recirculation system based on ejector technologyfor solid oxide fuel cell hybrid applications.The analysis presented here has been divided into three parts: (i) ejector design taking into account all the thermodynamic, fluid dynamicand chemical constraints, such as steam to carbon ratio (two ejector geometries have been considered: constant area mixing section,constant pressure mixing section); (ii) stand-alone ejector design and off-design performance analysis; (iii) influence on the whole hybridsystem-SOFC, reformer, anode recirculation-design and off-design performance of the ejector primary flow conditions (hybrid systempart-load conditions).
