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 cells (SOFCs) emerge as an alternative power generation system for high-scale stationary application and power plant station. The SOFC consumption leads to the high-efficiency energy production that forms variety of fuels up to 60% energy conversion; the operation system does not involve the burning process and minimizes the air pollution. Also, the aptitude to provide the cogenerative energy production from the heat waste during the operation process serve SOFC as an attractive green technology and environmentally friendly. However, the SOFC consumption remains limited for transportation and portable applications because the simple design of power source compartment is still the major hurdle in each SOFC component development and commercialization. Therefore, the appropriate fabrication method of each SOFC component is important to achieve the reliability of the SOFC application for the small-scale power generation design. In this paper, an overview of the design types and SOFC components and properties following electrode, electrolyte, interconnect and sealant are discussed and summarized. As the thirdgeneration fuel cells, which entice the commercialization stage, this paper concentrates more on the fabrication method of each SOFC components that were explored including the working principle, advantage, disadvantage and several previous works on each fabrication method, which are described to finding the appropriate fabrication method toward lowering the operating temperature and develop the simple design of SOFC power sources system for the transportation and portable application. The targeted market power production of SOFC system for transportation application is about 5 kW and 250 W for portable application.

Yttria-doping strategies of strontium cobaltite (SrCoO 3-δ ) have been systematically investigated as high-performance cathode materials for anode-supported solid oxide fuel cells. Sr 0.95 Y 0.05 CoO 3-δ (SYC), SrCo 0.95 Y 0.05 O 3-δ (SCY), and Sr 0.95 Y 0.05 Co 0.95 Y 0.05 O 3-δ (SYCY) were prepared by the citrate complexation sol-gel method. The crystal structures, oxygen desorption characterizations, electronic conductivities, and electrochemical performances were studied. The research result suggested that yttria doping into the A-site of SrCoO 3-δ (SYC) exhibited the highest electronic conductivity ($580 S cm À1 ), and the suppression of the oxygen vacancies results in the poor performance of oxygen reduction reaction (ORR) activity. The yttria doping into the B-site of SrCoO 3-δ (SCY) inhibits the oxygen desorption related to the Co 3+ to Co 2+ and electronic conductivity. The co-doping yttria of SrCoO 3-δ (SYCY) shows the lowest areaspecific resistances (0.147 Ω cm 2 at 600 C) and lowest activation energy (103.8 KJ mol À1 ). The ORR processes of SYC, SCY, and SYCY electrodes were analyzed by the distribution of relaxation time (DRT) technique. The I-V and I-P performances of SYCY cathode based on the anode-supported single fuel cell were also being exploited, and the peak power density of this cell is 1005 mW cm À2 at 650 C. The encouraging results suggest that SYCY is a candidate reduction electrode for solid oxide fuel cell.
