“…In this case, the chromium volatilisation from the Cr-Mn spinel could be as follows [79,80] The precipitation of this oxide blocks the active sites for oxygen reduction at the cathode/electrolyte interface, thus degrading the cell performance. In the case that the cathode is LSM, the oxide (Cr,Mn)3O4 can also be formed at the interface between the cathode and electrolyte [81,82]. This problem can be reduced by forming the oxide scale that exhibits low chromium volatilisation rate, which can be done by adding some alloying elements, by pre-oxidation before using the alloy in service, or by appropriate coating.…”

The chapter introduces components and working principle of solid oxide fuel cells (SOFCs). It is followed by the explanation on the choices of materials focussing on ferritic stainless steels. The review is further made on the required properties of these steels, i.e. low oxidation rate, low chromium species volatilisation rate, high electrical conductivity and good scale adhesion. For the oxidation aspect, the behaviour of stainless steel interconnect in cathode, anode (hydrogen and biogas), and dual atmospheres are described. Surface modification by pre-oxidation and coatings to improve the oxide electrical conductivity and to reduce chromium species volatilisation is finally reviewed.

“…For example, the corrosion of cathode is formed during the long term working condition due to exposure to carbon dioxide and humidity in the air. 44 The perovskitebased electrode is the common type material used in SOFC application and the common electrode is strontium-doped lanthanum manganite (LSM). 45 The advantages of LSMbased electrode are the high conductivity property until 100 S cm -1 at the 600°C and the coefficient of thermal expansion well matched with YSZ electrolyte (12.5 × 10 -6 K -1 ).…”

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.

“…Solid oxide fuel cells (SOFCs) are most efficient electrochemical devices which convert chemical energy into electricity with heat and water as a by-product. SOFCs are considered as eco-friendly since there is no production of sulfur or nitrogen oxides (only CO 2 ) along with fuel flexibility (H 2 , CO, hydrocarbons and biogases) [1][2][3] . Since, the high operating temperature of SOFC leads to degradation, coefficient of thermal expansion mismatch, electrode sintering and catalyst poisoning among the components of SOFCs [1][2][3] .…”
