“…44 Although difficult and time consuming to develop, three-dimensional physics-based modeling can play an important role in reactor design. Kattke et al 45 developed a comprehensive computational fluid dynamics model for a tubular solid-oxide fuel cell stack. Kee et al 46 developed radiation configuration factors to model alternative tube-stack arrangements.…”

Proton-conducting ceramics (protonic ceramics) form the basis for applications that include intermediate-temperature (e.g., $500$--$700$~$^\circ$C) fuel cells, electrolyzers, and membrane reactors. The electrolyte membranes are typically perovskites such as heterovalently doped barium cerates and zirconates (e.g., BaCe$_{1-x-y}$Zr$_x$Y$_y$O$_{3-\delta}$, BCZY; and BaCe$_{1-x-y-z}$Zr$_x$Y$_y$Yb$_z$O$_{3-\delta}$, BCZYYb). Although the materials are dominantly proton conductors, they are mixed ionic-electronic conductors (MIEC) with oxygen-ion and small-polaron mobility. The present paper is concerned primarily with steam-electrolysis applications with the reactors using tubular cell configurations. An important advantage of the protonic-ceramic cells is that they can produce nearly dry hydrogen. Each tubular cell is comprised of a negatrode (electrolysis cathode), proton-conducting electrolyte membrane, and a positrode (electrolysis anode). The tubular cells are typically supported on the relatively thick (order of one millimeter) composite negatrode, with thin (order tens of microns) external membrane and positrode layers. The paper explores considerations for scaling from laboratory-based demonstrations to deployable technology.

“…Kattke et al [22] modelled highly integrated SOFCbased system with 3D approach combined with 1D model of a tubular SOFC stack. In the work quasi-one-dimensional model was used to simulate balance of plant (BoP) components, including catalytic partial oxidation fuel processor and tail gas combustor.…”

This paper provides a review of modelling techniques applicable for system-level studies to account for physical, chemical, and material properties of solid oxide fuel cells. Functionality of 0D to 3D models is discussed and selected examples are given. Author provides information on typical length scales in evaluation of power systems with solid oxide fuel cells. In each section, proper examples of previous studies done in the field of 0D–3D modelling are recalled and discussed.

“…The hydraulic networks approach is also applicable to SOFC stack modeling under electric load conditions. Computational fluid dynamic system can be also used for system integration [2]. The coupling different models in one simulator can provide insight into operation of system components such as BoP devices, fuel processor, tail gas combustor, and SOFC stack.…”

“…It should be noted that, to distinguish between selected systems scales, terms micro and small were introduced. In the EU Combined Heat and Power directive [1] the earlier term refers to units with nominal power output 50 kW el , while in literature it usually covers systems with nominal power output of single kW el [2,3,4]. The later usually refers to system with output of tens of kW el .…”
