“…The limitation of CCO and YSZ combination is only compatible at a temperature of 800°C or below. Lee et al 86 determined the Ni/Ni-Ce 0.8 Sm 0.2 O 1.9 (SDC) anode/YSZ-SDC bi-layer electrolyte/Lantinum based support layer on porous YSZ ceramic. Thus, the improvement has been reported with decreasing in the area specific resistance (ASR) from 13.06 U cm 2 to 0.60 U cm 2 at 750°C.…”

“…The intermix layer present in the interface of Ni-YSZ and YSZ electrolyte has been proven by Secondary Neutral Mass Spectrometry analysis. Lee et al 86 determined the Ni/Ni-Ce 0.8 Sm 0.2 O 1.9 (SDC) anode/YSZ-SDC bi-layer electrolyte/Lantinum based support layer on porous YSZ ceramic. The various loading of poly (methyl methacrylate; PMMA) has been studied to get various pores of YSZ microstructure ceramics.…”

Solid Oxide Fuel Cells (SOFCs) are an electrochemical energy converter that receives the world's attention as a power generation system of the future owing to its flexibility to consume various types of fuels, low emission of greenhouses gases, and having high efficiency reaching over 70%. A conventional SOFCs operates at high temperature, typically ranges between 800 to 1000°C. SOFCs use yttria-stabilized zirconia (YSZ) as the electrolyte, which exhibits excellent oxide ion conductivity in this temperature range. However, this temperature range poses an issue to SOFCs durability, as it leads to the degradation of the cell components. In addition, SOFCs application is limited and difficult to implement for the transportation sector and portable appliance. A viable solution is to lower the SOFCs operating temperature to intermediate (600 to 800°C ) or low (<600°C) operating temperature. The benefit of this way, cell durability will improve, as well as other advantages such as facilitates handling, assembling, dismantling, cost reduction, and expanded the SOFCs application. Nonetheless, the key challenge for the issue is finding suitable electrolyte, as YSZ have lower ionic conductivity at low and intermediate temperature range. The aim of this paper is to review the status and challenges in the attempts made to modify YSZ electrolyte within the past decade. The resulting ionic conductivity, microstructure, and densification, mechanical and thermal properties of these 'new' electrolytes critically reviewed. The targeted conductivity of modification of YSZ electrolyte must be exceeded >0.1 S cm -1 to enable high performance of SOFCs power generation systems to be realized for transportation and portable applications. Based on our knowledge, this paper is the first review which focused on the recent status and challenges of YSZ electrolyte towards lowering the operating temperature.

The solid oxide fuel cell (SOFC) is one of the most promising devices for getting electrical energy. There are a lot of advantages in the use of SOFCs such as their efficiency, higher electrical and thermal power production and reduction of the emission of polluting gases. Modeling the SOFC at downscale is one of the most important challenges in fuel cell (FC) research. Knowing the behavior of materials to this scale is a helpful tool to predict the physical and chemical phenomena within the FCs, improve their efficiency and reduce material costs. At micro-and mesoscale, Lattice Boltzmann Method (LBM) appears as a powerful tool for modeling fuel cells. LBM has been proven suitable for solving several physical phenomena in complex geometries such as porous media. Using the D2Q9 LBM scheme, the velocity field for a selected section of an SOFC cathode is determined. This velocity field is shown in 2D and 3D graphics. The porosity and tortuosity for this selected region are calculated and compared with previous results.

“…Increasing industrial demand for novel and economically beneficial electronic devices strongly influences the development of porous ceramics' fabrication. Porous ceramics are successfully applied as piezoelectrics for ultrasound transducers [9], as components of SOFCs [10,11] or as components of thermo-ceramics modules for waste energy harvesting [12]. The last group of applications is the refractory one.…”
