Abstract
In this paper, a hierarchical model library of natural gas internal reforming (IR) solid oxide fuel cells (SOFCs) is developed to reflect a multi-level modeling design. First, two types of positive electrolyte negative (PEN) models are presented, which take into account the electromotive force of multi-component fuel and H2/CO joint electrochemical oxidation. Secondly, an advanced PEN model is introduced for better prediction at high fuel utilization. Thirdly, an approximate analytical PEN model is introduced to achieve a balance between accuracy and speed. Cell-level modeling provides boundary conditions for PEN-level models via a unified description of flow and heat transfer in both planar and tubular geometries. Unlike quasi-equilibrium and lumped cell-level models, distributed modeling reveals a significant difference between outlet gas temperatures and average solid temperature, especially under countercurrent flow. Based on analytical view factors, the detail ed radiation heat transfer model shows greater uniform distribution of current density and solid temperature. Upon validation, the multi-level SOFC model library constitutes the main component of the modular simulation platform for IRSOFC-GT (gas turbine) hybrid generation systems in a gPROMS® environment.

Prof. Eric Croiset
Eric Croiset is a professor in Chemical Engineering at the University of Waterloo, Ontario, Canada. His research is in the field of clean energy, more specifically in three areas: 1) catalyst development/reactor design for hydrogen/syngas production, 2) solid oxide fuel cell (SOFC), and 3) Greenhouse gas mitigation using carbon capture and sequestration (CCS). Prior to his appointment at the University of Waterloo, 11 years ago, he worked for Natural Resources Canada in Ottawa (CANMET laboratories). He holds a PhD from the University of Orleans, France, in Physical-Chemistry, and after graduation in 1995 did a postdoc at Sandia National Laboratories in Livermore, California, USA. Dr Croiset was a visiting professor at Chulalongkorn University in Bangkok, Thailand, and spent a sabbatical year at Tsinghua University, Beijing, China, working with Professor Cai on SOFC and CO2 capture processes. He is currently the Associate Chair of Undergraduate Studies in the Chemical Engineering Department at Waterloo and also participates actively in a newly established University of Waterloo campus in Dubai, United Arab Emirates.
