The WGSR in a mixed protonic-electronic conducting SrCeo.9Euo.i03. membrane coated on a Ni-SrCeOa. support was studied by Li et al. [66], At 900°C a 46% increase in CO conversion was achieved, with the feed stream having a H2O/CO ratio of 2. 

Ceramic electrochemical reactors are currently undergoing intense investigation, the aim being not only to generate electricity but also to produce chemicals. Typically, ceramic dense membranes are either pure ionic (solid electrolyte SE) conductors or mixed ionic-electronic conductors (MIECs). In this chapter we review the developments of cells that involve a dense solid electrolyte (oxide-ion or proton conductor), where the electrical transfer of matter requires an external circuitry. When a dense ceramic membrane exhibits a mixed ionic-electronic conduction, the driving force for mass transport is a differential partial pressure applied across the membrane (this point is not considered in this chapter, although relevant information is available in specific reviews).
