Funding Information:
This paper reports the first plenum study of a 60-cell stack simulating planar solid oxide electrolysis cells (SOEC) with the FLUENT code and SOFC module [10] . This code was used for detailed SOEC modeling. Fluent Inc. was funded by the DOE National Energy Technology Laboratory (DOE-NETL) to develop a solid oxide fuel cell (SOFC) module for coupling to the core mass, momentum, energy, and species conservation and transport features of the FLUENT computational fluid dynamics (CFD) code. The SOFC module adds the electrochemical reactions and loss mechanisms and computation of the electric field throughout the cell. The FLUENT SOFC user-defined subroutine was modified for this work to allow for operation in the SOEC mode. Model results provide detailed profiles of temperature, Nernst potential, operating potential, anode-side gas composition, cathode-side gas composition, current density, and hydrogen production over a range of stack operating conditions. Ref. [11] has details of the FLUENT code and numerical model. Results of the numerical model are shown in this article.

N2 - A three-dimensional computational fluid dynamics electrochemical model was developed to model high-temperature electrolysis stack performance and steam electrolysis. The model was made of 60 planar cells stacked on top of each other operated as solid oxide electrolysis cells. A solid-oxide fuel cell model added the electrochemical reactions and loss mechanisms and computation of the electric field throughout the cell. The model results provided detailed profiles of temperature, Nernst potential, operating potential, activation overpotential, anode-side gas composition, cathode-side gas composition, current density, and hydrogen production over a range of stack operating conditions. Variations in flow distribution, and species concentration were discussed. The end effects of flow and per-cell voltage were considered. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2008).
