“…For design optimisation, commercial Computational Fluid Dynamic (CFD) software has been used by Herring et al [15] to propose a three dimensional SOEC modelling. Freshly, Gondrin et al [16] have improved the two dimensional CFD description by implementing the DGM approach to calculate H 2 and H 2 O distribution through porous cathode as a function of microstructure.…”

“…Two forms of this equation are regularly employed in models: the classical Butler-Volmer equation [11], that accounts for the activation effects, and the generalized Butler-Volmer equation [10,12], that accounts for both activation and concentration effects. The first equation is obtained from the second by considering that the concentrations of chemical species do not vary across the electrode.…”

Theoretical considerations on the modelling of transport in a three-phase electrode and application to a proton conducting solid oxide electrolysis cell. International Journal of Hydrogen Energy, Elsevier, 2012, 37 (16) The paper presents a complete numerical model for the prediction of mass and charge transfer inside electrolysis cells and fuel cells working at high temperature and using cermets as electrodes. It also discusses some assumptions taken in fuel cells or electrolysis cells modelling.I think that the problems dealt in this paper are in perfect match with the topics covered by the International Journal of Hydrogen Energy. Indeed many articles that were published in the journal served as a basis for this work.Meng Ni, from the University of Hong Kong, M.M Hussain, from the University of Waterloo and Anchasa Pramuanjaroenkija, from the University of Miami, would represent in my view relevant reviewers for this paper. As specialists in fuel cells and electrolysis cells modelling, they can rigorously evaluate the scientific content of this paper. Moreover, several assumptions they use for their models are discussed in the paper.I am fully available from the first of January to deal with the reports of the reviewers.I will be pleased to supply any further information should it be required.Yours sincerely, Mikael DumortierCover LetterDemonstration of continuity equations for mass and charge inside a cermet electrode *Manuscript Click here to view linked References Abstract

“…Based on the work of Grondin et al ,

D_{K, ϕ}^{eff}

can be estimated by using the following formula:

D_{K, ϕ}^{italiceff} = d_{p} \frac{ε}{3 τ} \sqrt{\frac{8 italicRT}{π M_{i}}}

d_{p} = \frac{2}{3} \frac{ε}{1 - ε} d_{g}

SUMMARYA unitized regenerative solid oxide fuel cell (URSOFC) can be considered as a next-generation power source and a storage device in the future since it can generate electricity in the SOFC mode and also produce H 2 /O 2 in the solid oxide electrolyzer cell (SOEC) mode. In this paper, a two-dimensional axisymmetric model is developed to simulate the characteristics of a URSOFC. The performance curves for an in-house button URSOFC under different operating temperatures of 600, 700, and 800 C are measured to validate the present model. Both the measured data and the prediction results reveal the beneficial effects of higher temperature on the cell performance. Based on the results of numerical simulations, the majority of the fuel gas is consumed at the interface of the electrolyte and the electrode, causing a great fuel concentration gradient near the interface. In addition, the predicted cell performance curves in both the SOFC and the SOEC modes correspond well with the measured data, demonstrating the applicability of this model in a button URSOFC.
