“…Although Ni is an excellent catalyst for both electrochemical oxidation reaction and reforming reaction in producing hydrogen and syngas (H2 and CO) [44][45][46][47][48], Ni also prone to carbon deposition. Hence, Ni-free anode with alternative metal [6,17,49] and perovskites material [50,51] On the other hand, Singh et al [42] and Lay et al [61] reported no significant performance difference and higher amounts of carbon observed on the Sn doped cells compared to the undoped cells with either low steam to carbon ratio. Troskialina et al [27] and Jiang et al [60] tested Sn-Ni/YSZ with dry biogas fuel instead of humidified hydrocarbon fuel.…”

“…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

View full text Add to dashboard Cite

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).
