Abstract:

Protonic ceramic fuel cells (PCFCs) are expected to gain significant advantage from the use of Co-free cathodes. This shift can lead to reduced manufacturing costs and enhance durability performance. In our previous study, the investigation compared the power generation characteristics of PCFCs with BaZr0.8Yb0.2O3-δ (BZYb) electrolytes utilizing cathodes composed of La0.6Sr0.4FeO3-δ (LSF) as a Co-free cathode material and La0.6Sr0.4CoO3-δ (LSC) or La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) as Co-containing cathode materials composited with BZYb. Consequently, the PCFC with an LSF-BZYb cathode exhibited l

Protonic Ceramic Fuel Cell (PCFC) is expected to be the next-generation fuel cell due to its higher energy conversion efficiency. We evaluated the electric efficiency using a Φ60mm anode supported BZYb cell and a newly designed jig. The Φ60mm BZYb cell performed almost as well as the Φ20mm cell, and the maximum power reached 7 W at 12.9 A at 600ºC. In addition, we obtained the cell performance of 0.3 A cm–2 current density under various Uf (fuel utilization) condition. We demonstrated that a BZYb based PCFC could be operated at a high Uf condition (i.e., Uf = 90%), and the maximum electric eff

Abstract:

In protonic ceramic fuel cells (PCFCs), the use of cobalt-free cathodes is expected to reduce manufacturing costs and improve durability performance. However, cobalt-free cathodes generally tend to have poor power generation performance due to their lower catalytic activity than cobalt-containing cathodes. Therefore, based on a previous study in which higher power generation performance was obtained with SOFCs using La0.65Ca0.35FeO3−δ (LCaF) than with SOFCs using La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) containing cobalt, we focused on LCaF as a cobalt-free cathode.

Abstract:

Protonic ceramic fuel cells (PCFCs) are expected to be a highly efficient next-generation fuel cell because the fuel is not diluted by the generated water vapor during power generation. In the past research, we have found that Yb-doped BaZrO3 (BZYb) is promising in terms of the durability against CO2, proton conductivity, and less reactivity with NiO used for the fuel electrode. We are currently developing improvement of power generation efficiency and durability of PCFCs using BZYb electrolyte.

The article is devoted to the confrontation between the Soviet and German troops on the passes of the Bzyb Range in August – September 1942. As is known, by this time the Wehrmacht forces had suffered serious de-feats from the Soviet armed forces near Moscow, Rostov, and Tikhvin. The confrontation took a protracted character, so, planning the summer campaign of 1942, the German command decided to seize the most im-portant economic areas in the south of the USSR. The battle for the Caucasus included both the capture of the region’s passes and access to the Black Sea. It was precisely such fight

Joint analysis of remote sensing imagery and in situ data suggest that the observed concentric rings are surface manifestations of high-frequency internal waves generated in the vicinity of the river mouth.

Abstract Multiple myeloma (MM) is a malignancy of terminally differentiated clonal plasma cells displaying significant molecular heterogeneity with 7 subgroups defined by gene expression profiling (GEP). Our previous work showed that both the MS and MF subgroups associated with inferior survival (Zhan et al, Blood 2006). Furthermore, clinical studies have demonstrated that the addition of the proteasome inhibitor (PI) bortezomib (Bzb) to high dose melphalan based regimens provided a major advantage to patients in MS subgroup while patients in the MF subgroups (including C-MAF and MAFb) did not

For practical utilization of proton-conducting ceramic fuel cells and electrolyzers, it is essential to lower the sintering temperature and processing time of BaZrO3-based proton conductors. We investigated the effect of sintering temperature and time on the structural and electrochemical properties of dense BaZr0.8Y0.2O3−δ (BZY) prepared by a solid-state reactive sintering process, using NiO as a sintering aid. The sintered BZY prepared from the micronized precursor powder exhibited a density higher than 93%, and an average grain size in the range of 0.6 to 1.4 μm. The orthorhombic BaY2NiO5 p

Ni-BZY (yttrium-doped barium zirconate) has drawn recent interest for application in protonic ceramic fuel cells (PCFCs) due to BZY’s superior protonic conductivity and stability in reforming environments containing CO2 and H2O. Additionally, Ni and BZY form unique nano/microstructures thought to synergistically facilitate reforming. While PCFCs with Ni-BZY anodes have demonstrated stable long-term performance, little is known about the material’s transformations during operation and subsequent impact on electrochemical metrics. To address this knowledge gap, we constructed PCFCs consisting of

Abstract Inhibition of Wnt/β-catenin/T-cell factor (TCF) signaling induces proliferation of mesenchymal stem cells and/or suppresses their differentiation into osteoblasts (OBs). Osteolysis in multiple myeloma (MM) is related to the suppression of canonical Wnt signaling caused by DKK1, a soluble inhibitor of this pathway secreted by MM cells. Bortezomib (Bzb) can induce OB differentiation in vitro and in vivo and its anti-MM efficacy linked to bone anabolic effects. However, the molecular basis of the action of Bzb on bone is not completely understood. In the present study, we show that Bzb p

The stresses will in turn impact the electrical conductivities, which is often omitted in current studies.

Solid oxide fuel cell (SOFC) and related Protonic Ceramic Fuel Cell (PCFC) technologies have demonstrated significant promise for the efficient and clean electrochemical conversion of stored energy held in a wide variety of renewable fuels, decreasing dependence on traditional fossil fuels. The high efficiencies of both devices arise from the direct chemical-to-electrical energy transformation, achieved without moving parts and the losses inherent to combustion technologies.

These materials were characterized by X-ray diffraction, scanning electron microscopy, and impedance spectroscopy. The combination of BZY with alkali metal carbonate promotes the densification and enhances the ionic conductivity, which reaches 87 mS·cm−1 at 400 °C for the BZY–LNK40 composite.

Proton conducting solid oxide electrolysis cells (H-SOEC) have advantages over its oxygen-ion-conducting (O-SOEC) counterpart due to lower operating temperature (e.g. 300-700oC), relatively lower activation energy, and easier gas separation [1, 2]. However, it suffers from low Faradaic efficiency led by the internal current leakage. Protonic ceramics like BaZr0.90Y0.10O3 (BZY) are generally mixed proton, oxygen ion and electron hole conducting oxides, in which the transference number of each charge carrier depends on the material composition, operating temperature, atmosphere, and polarization
