“…Based on the derivation, exchange current density formulations are proposed for Ni and Pt surfaces that are free from arbitrary order dependency on the partial pressures of reactants and products. The derived Butler-Volmer equation together with the Butler-Volmer equation for oxygen charge transfer presented in [6] we have reproduced the experimental observations of Tao et al [3,4] and Ebbesen and Mogensen [2]. The model equations are further used to analyze the behavior of single channel.…”

A modified Butler-Volmer equation for the reduction of CO 2 by considering multi-step single electron transfer reactions is presented. Exchange current density formulations free from arbitrary order dependency on the partial pressures of reactants and products are proposed for Ni and Pt surfaces. Button cell simulations are performed for Ni-YSZ/YSZ/LSM, Pt-YSZ/YSZ/Pt, and Pt/YSZ/Pt systems using two different electrochemical models and simulation results are compared against experimental observations. The first electrochemical model considers charge transfer reactions occurring at the interface between the electrode and dense electrolyte and the second model considers the charge transfer reactions occurring throughout the thickness of the cermet electrode. Single channel simulations are further performed to asses the O 2 production capacity of CO 2 electrolysis system.

Various additives to Ni–Fe systems are studied as cermet cathodes for CO2 electrolysis (973–1173 K) using a La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) electrolyte, which is one of the most promising oxide‐ion conductors for intermediate‐temperature solid‐oxide electrolysis cells in terms of ionic‐transport number and conductivity. It is found that Ni–Fe–La0.6Sr0.4Fe0.8Mn0.2O3 (Ni–Fe–LSFM) exhibits a remarkable performance with a current density of 2.32 A cm−2 at 1.6 V and 1073 K. The cathodic overpotential is significantly decreased by mixing the LSFM powder with Ni–Fe, which is related to the increase in the number of reaction sites for CO2 reduction. For Ni–Fe–LSFM, much smaller particles (<200 nm) are sustained under CO2 electrolysis conditions at high temperatures than for Ni–Fe. X‐ray diffraction analysis suggests that the main phases of Ni–Fe–LSFM are Ni and LaFeO3; thus, the oxide phase of LaFeO3 is also maintained during CO2 electrolysis. Analysis of the gaseous products indicates that only CO is formed, and the rate of CO formation agrees well with that of a four‐electron reduction process, suggesting that the reduction of CO2 to CO proceeds selectively. It is also confirmed that almost no coke is deposited on the Ni–Fe–LSFM cathode after CO2 electrolysis.
