“…In the present study, the Nernst potentials for H 2 and CO fuels are calculated separately using their respective gas partial pressures [25,29,30]. In operation, the potential V can be calculated as the equilibrium potential (E, determined from Gibbs free energy change of the reactions [25]) subtracted by all overpotential losses [25,29,30]. …”

“…After investigating CO 2 electrolysis [31], Ni et al [20,32] have recently developed a kinetic model taking into account the CO 2 electro-reduction and the reverse WGS reaction. Finally, based on the initial work of Hecht et al [33] in SOFC mode, some micro models have been proposed by splitting the whole electrochemical process of co-electrolysis [34,35] or CO 2 electrolysis [36] in a sequence of elementary steps.…”

This work details an in‐house 2D electrochemical and thermal model of solid oxide electrolysis cell (SOEC) dedicated to the simultaneous electrolysis of steam and carbon dioxide. The apparent exchange current densities for both H2O and CO2 electrochemical reductions have been fitted on single electrolysis polarization curves obtained on a standard cathode supported cell (CSC). By using these values, predictive simulations have been performed in a co‐electrolysis mode. The results have been compared to experimental data obtained in the same conditions. A good agreement is found between the simulated points and the experimental polarization curves, meaning that the model stands to predict accurately the SOEC response in co‐electrolysis mode. Simulations have been performed to investigate co‐electrolysis mechanisms in terms of partial pressures, current densities, and overpotentials distributions along the cell. The relative influence of both water gas shift (WGS) reaction and CO2 electrolysis on the global CO production is also discussed.

Abstract:Compact reformers (CRs) are promising devices for efficient fuel processing. In CRs, a thin solid plate is sandwiched between two catalyst layers to enable efficient heat transfer from combustion duct to the reforming duct for fuel processing. In this study, a 2D heat and mass transfer model is developed to investigate the fundamental transport phenomenon and chemical reaction kinetics in a CR for hydrogen production by methane steam reforming (MSR). Both MSR reaction and water gas shift reaction (WGSR) are considered in the numerical model. Parametric simulations are performed to examine the effects of various structural/operating parameters, such as porosity, permeability, gas velocity, temperature, and rate of heat supply on the reformer performance. It is found that the reaction rates of MSR and WGSR are the highest at the inlet but decrease significantly along the reformer. Increasing the operating temperature raises the reaction rates at the inlet but shows very small influence in the downstream. For comparison, increasing the rate of heat supply raises the reaction rates in the downstream due to increased temperature. A high gas velocity and permeability facilitates gas transport in the porous structure thus enhances reaction rates in the downstream of the reformer.
