“…As mentioned above, YSZ shown higher electrical conductivity with high operating temperature and lasting mechanical behavior. Perovskite oxide electrodes materials containing of lanthanum, have the reacting property at high operating temperature which aims of the formation of layers (La 2 Zr 2 O 7 ) with high resistivity [24,31]. LSGM-NiO composite material is less compatible for anode applications, while for perovskite based cathodes, high order of compatibility of LSGM and higher ionic conductivity with lanthanum transition oxide [24,32].…”

There is a growing interest in solid oxide fuel cells (SOFCs) technology among the researchers a promising power generation with high energy efficiency, inflated fuel flexibility, and low environmental impact compared to conventional power generation systems. SOFCs are devices in which the chemical energy is directly converted into electrical energy with negligible emission. SOFCs have low pollution characteristics, high efficiency (~ 60%), and possess expanded fuel selection with little environmental effects. A single cell component of SOFCs is consisting an anode, cathode and an electrolyte which are stacked layer by layer to produce higher amount of power. The dense ceramic electrolyte transporting O2− ions and fills the space between the electrodes material. Redox reaction occurred at the electrodes side in the presence of fuels. The operating temperatures of SOFCs of 600–1200 °C which produced heat as a byproduct and fast electro-catalytic activity while using nonprecious metals. Many ceramic materials have been investigated for SOFCs electrolyte. Yttria-stabilized zirconia (YSZ) material was extensively used as dense electrolyte in SOFCs technology. In this review, the article presents; overview of the SOFCs devices and their related materials and mostly reviewed newly available reported.

“…The presence in the B-site of transition metals with multiple oxidation states is of primary importance because it largely determines the electrocatalytic properties and stability upon redox cycling [ 10 , 11 ]. The different perovskite materials proposed to date as anodes can be found in several reviews [ 12 , 13 ], in which their main advantages and disadvantages are highlighted.…”

A Novel, Simple and Highly Efficient Route to Obtain PrBaMn2O5+δ Double Perovskite: Mechanochemical Synthesis

2021

In this work, a mechanochemical route was proposed for the synthesis of the PrBaMn2O5+δ (PMBO) double layered perovskite phase. The mechanochemical reaction between Pr6O11, BaO2, and MnO powders with cationic stoichiometric ratios of 1/1/2 for Pr/Ba/Mn was performed using high-energy milling conditions in air. After 150 min of milling, a new phase with perovskite structure and cubic symmetry consistent with the A-site disordered Pr0.5Ba0.5MnO3 phase was formed. When this new phase was subsequently annealed at a high temperature in an inert Ar atmosphere, the layered PrBaMn2O5+δ phase was obtained without needing to use a reducing atmosphere. At 1100 °C, the fully reduced layered PrBaMn2O5 phase was achieved. A weight gain was observed in the 200–300 °C temperature range when this fully reduced phase was annealed in air, which was consistent with the transformation into the fully oxidized PrBaMn2O6 phase. The microstructural characterization by SEM, TEM, and HRTEM ascertained the formation of the intended PrBaMn2O5+δ phase. Electrical characterization shows very high electrical conductivity of layered PBMO in a reducing atmosphere and suitable in an oxidizing atmosphere, becoming, therefore, excellent candidates as solid oxide fuel cell (SOFC electrodes).

“…Conventional FCs, including SOFCs and PCFCs, are comprised of a minimum of three functional components (layers): electrolyte, cathode and anode. Each layer requires its own unique processing regime [17][18][19]. In terms of the electrode-supported configuration of FCs, a thin electrolyte layer is formed onto a Ni-based anode and then these two layers are jointly fired at high temperatures to form a half-cell, combining the porous anode substrate and dense electrolyte.…”

One-Step Fabrication of Protonic Ceramic Fuel Cells Using a Convenient Tape Calendering Method

The present paper reports the preparation of multilayer protonic ceramic fuel cells (PCFCs) using a single sintering step. The success of this fabrication approach is due to two main factors: the rational choice of chemically and mechanically compatible components, as well as the selection of a convenient preparation (tape calendering) method. The PCFCs prepared in this manner consisted of a 30 µm BaCe0.5Zr0.3Dy0.2O3–δ (BCZD) electrolyte layer, a 500 μm Ni–BCZD supporting electrode layer and a 20 μm functional Pr1.9Ba0.1NiO4+δ (PBN)–BCZD cathode layer. These layers were jointly co-fired at 1350 °C for 5 h to reach excellent gas-tightness of the electrolyte and porous structures for the supported and functional electrodes. The adequate fuel cell performance of this PCFC design (400 mW cm−2 at 600 °C) demonstrates that the tape calendering method compares well with such conventional laboratory PCFC preparation techniques such as co-pressing and tape-casting.
