High temperature electrolyzer based on solid oxide co-ionic electrolyte: A theoretical model

BaCeO3: Materials development, properties and application

“…It was found that partial substitution of cerium with zirconium is one of the best ways to optimise transport and mechanical properties and also This paper is devoted mainly to the applied aspects of the synthesis and application of proton conductors based on barium cerate. However, it is noteworthy to mention that these systems are of significant fundamental interest for researchers from the viewpoint of mechanisms of conductivity [186,187,212,[354][355][356][357], H/D isotope effects [358][359][360][361][362], macrokinetic and thermodynamic aspects of SOFCs based on co-ionic or pure protonic conductors [363][364][365][366][367][368][369][370]. It can be concluded that although at the present time many technical difficulties and problems related to the optimization of the target properties of BaCeO 3 -based proton conductors have been solved, the quest for the optimal protonic (co-ionic) materials…”

Static–dynamic modelling of the electrical behaviour of a commercial advanced alkaline water electrolyser

“…Ni et al [73] developed a temperature dependent electrochemical model. The model simulations were validated through experimentation reaching temperatures of 1273 K. Demin et al [74] built a fully theoretical model considering both the electrolyte anionic and cathodic conductivity. Laurencin et al [75] built a 2D multi-physic model to analyse the performances of a solid oxide electrolysis cell stack.…”

Technological development of hydrogen production by solid oxide electrolyzer cell (SOEC)

“…Demin et al [134] developed a theoretical model to study the performance of SOEC based on solid oxide co-ionic electrolyte. It was found that the counter flow mode (reactants) was preferred to co-flow mode.…”
