Summary: This study experimentally investigated the influence of operation temperature, inlet gas composition, current density, and anode thickness on the methane steam reforming reaction over nickel yttria-stabilized zirconia anodes in solid oxide fuel cells. The results were analyzed using two kinetic models, with positive methane reaction order and negative impact of steam partial pressure on the reaction rate being observed. The evaluation of the models suggested that the Langmuir-Hinshelwood kinetic model performed better due to its additional parameters.

Summary: In order to improve the contact between the electrolyte and carbon fuel in SO-DCFCs, molten metals and molten salts were used in the anode chamber. The molten medium not only allows the transportation of oxygen ions to oxidize the carbon particles, but also serves as a redox mediator to enhance the kinetics of the electrochemical oxidation of carbon. Additionally, using a liquid metal/salt anode can mitigate the negative effects of carbon contaminants on cell performance.

Summary: This paper develops a transient numerical model to investigate the influence of the switching temperature on the SOFC warming-up process and proposes an optimal switching temperature considering different objectives. The results show that a lower switching temperature leads to a shorter warming-up time and greater energy efficiency, but also causes higher thermal shock. Using a multi-objective decision making approach, a compromise switching temperature is proposed as the optimal solution.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
