Solid oxide fuel cell Introduction

Physically, a solid oxide electrolyzer cells (SOEC) may be exactly the same cell as solid oxide fuel cell (SOEC) Solid Oxide Fuel Cells, Introduction as this cell type is fully reversible [1]. It can be used for CO2 electrolysis only but will most often be intended for electrolysis of a mixture CO2 and steam, H2O. This is called co-electrolysis of steam and CO2. The principle of both SOEC and SOEC is illustrated in Fig. 2.

During the course of the last century, it was realized that many properties of solids are controlled not so much by the chemical composition or the chemical bonds linking the constituent atoms in the crystal but by faults or defects in the structure. Over the course of time the subject has, if anything, increased in importance. Indeed, there is no aspect of the physics and chemistry of solids that is not decisively influenced by the defects that occur in the material under consideration. The whole of the modem silicon-based computer industry is founded upon the introduction of precise amounts of specific impurities into extremely pure crystals. Solid-state lasers function because of the activity of impurity atoms. Battery science, solid oxide fuel cells, hydrogen storage, displays, all rest upon an understanding of defects in the solid matrix.

Somehow the chemistry of the solid state has split off from the chemistry of the elements as organic chemistry did in the 19th century. Solid state chemistry is a fairly new discipline, which is concerned with atomic defects in solids and their action in chemical processes. As materials are atomic solids, solid state chemistry dominates materials chemistry. Solid state chemistry is not yet generally found in curricula of academic or technological chemistry, so Chapter 5 provides an introduction to the subject. Its contribution to materials chemistry is shown in Chapters 6, 8, 9, and 10. Solid electrolytes of Nernst-type sensors and solid oxide fuel cells are ionic conductors owing to the behavior of ionic defects.
