“…The distributed charge transfer model is validated with experimental data of Tao et al [4] at 1023 K for Pt-YSZ cermet electrode. The geometrical parameters remains the same as in the previous case with volume fraction of 31% for Pt and considers 97% CO 2 and 3% CO.…”

“…In the second model we assume that the electrochemical charge transfer reaction occurs throughout the thickness of the electrode. This model is explained in section 2.3 and is used to reproduce the experimental observation of Tao et al [4] for Pt-YSZ cermet electrode. Both models require Butler-Volmer equation in-order to evaluate electrochemical reaction rate at the three-phase interfaces, which is explained in the following section.…”

“…In a continuation work they have studied the same process in a Pt-YSZ cermet electrode and found the resulting current density to be higher than that of pure Pt electrode [4]. However, this result is obvious due to the distributed nature of three phase boundary and hence higher overall electrochemical reaction rates in a cermet electrode.…”

“…The model is used to reproduce the experimental observation of Tao et al [3] and Ebbesen et al [2]. Additionally, the developed Butler-Volmer equation is used along with a distributed charge transfer model and the results are validated by comparing the model predictions with the experimental observation of Tao et al reported in [4]. Furthermore, the Butler-Volmer equation is used to analyze isothermal single channel co-flow configuration.…”

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.

Electrodes with a maximal active site density are critical for high‐performance high‐temperature electrochemical cells (HTECs). One widely employed approach involves the use of porous nanostructures with a high surface‐to‐volume ratio. However, their active site densities inevitably decrease owing to particle aggregation induced at high temperatures, necessitating further development of electrode processing techniques. Taking Pt/yttria‐stabilized zirconia (YSZ) interface as a model system, a Pt nanostructured textile akin to the cantaloupe‐rind pattern with high mechanical integrity is fabricated. Application of an AC voltage to this textile electrode at an elevated temperature reduces the Pt particle size from submicron to 10–80 nm forming a nanocomposite with YSZ, accompanied by a 40‐fold increase in current density under high‐temperature water electrolysis conditions. Furthermore, the AC voltage application to a partially aggregated electrode restores its nano‐blended structure associated with the recovery of its activity. This technique is effective in counteracting particle aggregation on demand, providing an alternative approach to achieve high performance and extended lifetimes in HTECs.
