Summary: In this study, three different anode microstructures were fabricated in micro-tubular solid oxide fuel cells (MT-SOFCs) by using different polymer binders. A superior anode substrate with graded pore distribution was obtained by utilizing a PESf/PEI blend material as the polymer binder. The maximum power density of the cell fabricated by PESf/PEI blend polymer binder reached 630 mW center dot cm-2 at 750 degrees C, which is much higher than those of PEI polymer binder and PESf polymer binder at the same temperature. The improved electrochemical performance can be attributed to the accelerated gas transportation in the anode.

Summary: BaSrInFeO5 (BSIF) is a new cathode material designed for proton-conducting solid oxide fuel cells (SOFCs) by modifying the Ba2In2O5 proton conductor with Sr and Fe cations. Sr doping improves the chemical stability, formation of oxygen vacancies, and proton mobility of the material. Experimental studies and first-principles calculations demonstrate that an H-SOFC using the BSIF cathode achieves a high peak power density of 1192 mW cm-2 at 700 oC, surpassing previous reports. This study suggests that derived cathode materials from less-studied Ba2In2O5 could offer new material selections for H-SOFCs.

Summary: By synthesizing nominal PrxSr0.5MnO3-d materials, new Pr0.5Sr0.5MnO3-d (PSM50)+ PrO2_(x) composite cathodes for proton-conducting solid oxide fuel cells (SOFCs) were developed. The exsolution of PrO2_(x) particles was observed, increasing with the amount of Pr in PrxSr0.5MnO3-d. A Pr0.7Sr0.5MnO3-d (PSM70) cathode enabled the highest fuel cell output reported for H-SOFCs with manganate cathodes. The construction of a PSM50/PrO2 heterostructure interface accelerated the cathode oxygen reduction reaction (ORR) kinetics and demonstrated excellent electrochemical performance and chemical stability.

Summary: LiCoO2, a material widely used in Li-ion batteries, was found to be suitable as a cathode material for H-SOFCs. The evaporation of Li in LiCoO2 led to the in-situ formation of a LiCoO2+Co3O4 composite, which greatly enhanced the performance of the cathode in H-SOFCs. The formation of Co3O4 due to Li-evaporation decreased the formation energy of oxygen vacancies, resulting in improved cathode performance.

Summary: The study demonstrates that tailoring the electronic structure of perovskite oxide with Mo-doping leads to improvements in cathode materials for proton-conducting solid oxide fuel cells. The Mo-doping changes the electronic structure of the oxide, making the metal-oxygen bond less strong and the surface more active towards oxygen reduction, resulting in more feasible oxygen vacancy formation critical for protonation. The electric field induced by Mo-doping provides an additional driving force for proton movement, accelerating proton migration in the oxide and improving cathode performance.

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.

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.
