“…The ashes were calcined at 1300 °C for 12 h under air atmosphere to obtain good crystallization and remove carbon residues. BaZr 0.3 Ce 0.5 Y 0.2 O 3− δ (BZCY) and NiO powders were prepared using a similar synthesis procedure, as reported previously …”

“…Besides these perovskite oxides, Ruddlesden‐Popper (R−P) structure oxides with the formula of A n +1 B n O 3 n +1 also deserve great attention (A=alkaline earth, B=transition metal, and n =number of octahedral layers in perovskite‐like slabs, e. g., 1, 2, 3, n ). For instance, Sr 3 Fe 2 O 7− δ and its derivatives have been reported as good MPECs and shown outstanding electrochemical performances as cathodes for PCFCs . Liu and co‐workers reported Pr 2 NiO 4+ δ is a promising triple‐conductive anode material for proton‐based steam electrolysis cells .…”

Protonic ceramic fuel cells (PCFCs) have been proved as an efficient energy converter at intermediate temperatures. To accelerate the kinetics of the proton-involved oxygen reduction reaction (p-ORR), developing efficient and durable cathodes is of great importance for improving PCFCs. In this work, a new triple-layered Ruddlesden-Popper (RÀ P) structure oxide, Sr 3 EuFe 2.5 Co 0.5 O 10À δ (3-SEFC 0.5), was developed as a potential single-phase cathode for PCFCs, showing high oxygen nonstoichiometry and desirable structural thermal stability. By employing this highly active and stable single-phase cathode, the PCFC demonstrated unprecedented low polarization resistances and exceptionally great peak power densities, which were approximately 0.030 Ω cm 2 and 900 mW cm À 2 measured at 700°C, respectively. These findings not only manifest the effectiveness of optimal doping in improving the structural stability and electrocatalytic activity in the multi-layered perovskite family, but also highlight the great potential of using multi-layered RÀ P series oxides as highly active and durable catalysts for PCFCs.

“…Therefore, to meet all the requirements, the most common strategies adopted by various researchers are to form BaCe 1-x Zr x O 3 -based solid solution [28] , as shown in Table 1. Huan et al [29] have fabricated H-SOECs with BaCe 0.5 Zr 0.3 Y 0.2 O 3-δ (BCZY53) electrolyte layer and the electrolysis cells show relatively stable performance in short-term (30 h) testing.…”

“…One effective strategy to improve the stability of perovskite structure oxides in a humid atmosphere is to partially replace the alkaline earth elements by other elements with higher acidity, such as lanthanide elements. For example, to improve the stability of Sr 3 Fe 2 O 7-δ in high steam atmospheres, Huan et al [29,57] maintaining stable crystalline structure over 100 h in 20% H 2 0-air at 1073 K [58] . Recently, Norby et al [8] have investigated the chemical stability of mixed electronic and protonic conductors (Ba 1-…”

The proton-conducting solid oxide electrolysis cell (H-SOEC) is a promising device that converts electrical energy to chemical energy. H-SOECs have been actively studied in the past few years, due to their advantages over oxygen-ion-conducting solid oxide electrolysis cells (O-SOECs), such as lower operation temperature, relatively lower activation energy, and easier gas separation. A critical overview of recent progress in H-SOECs is presented, focusing particularly on the period from 2014-2018. This review focuses on three aspects of H-SOECs, namely the materials, modeling and current leakage in proton conducting oxide electrolytes. Specifically, the current leakage in proton conducting oxides, which is often neglected, leads to two problems in the studies of H-SOECs. One is the distortion of the electrochemical impedance spectra (EIS) and the other is low faradaic efficiency of electrolysis. Based on the comprehensive and critical discussion in these three sections, challenges in the development of H-SOECs are highlighted and prospective research in H-SOECs is outlined.Received: ((will be filled in by the editorial staff))Revised: ((will be filled in by the editorial staff))

A versatile explanation of mechanism of electroless plating process based on electrochemical reactions is presented [ 300 , 301 , 302 ]. The reducing agents are anodically oxidized on the catalyst surface while the electrons obtained are transferred to metal ions by a cathodically reduction.…”

View full text Add to dashboard Cite

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.
