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.

“…Presintered 3Y-TZP specimen were used for the preparation of ZrO 2 /glass composites by the infiltration of silica sols or glass slurries, respectively [28]. Al 2 TiO 5 was formed in NiO/YSZ SOFC anodes by infiltration of aluminum nitrate/titanium lactate aqueous solutions, and a heat treatment at 1400°C [29]. Additionally, non-oxide ceramics like C f /SiC-ZrC-ZrB 2 composites were produced by the infiltration of a boron containing sol into a C f /SiC fabric followed by the infiltration of a ZrB 2 melt [30].…”

composites can be obtained by the infiltration of molecular titanium precursors into presintered α-Al 2 O 3 (corundum) cylinders. Two titanium tetraalkoxides, and two dialkoxy titanium bis(acetylacetonates) serve as precursors for TiO 2 (rutile) and Al 2 TiO 5 (tialite). The precursors were infiltrated as ethanolic solutions. After sintering at 1550, 1600, and 1650°C, the prepared ceramics' properties were investigated by SEM, in-situ HT-XRD, and conventional XRD. Titanium tetraisopropoxide leads to the highest content of Al 2 TiO 5 in the composite. The more reactive the precursor, considering the Al 2 O 3 /precursor interface, the lower and more anisotropic the grain growth, the more homogeneous is the TiO 2 contribution and the higher is the content of Al 2 TiO 5 . Raising the sintering temperature causes an increase of the crystalline Al 2 TiO 5 con tent as well as of the grain growth. Moreover, the reactivity of the precursor molecule influences the Ti/(Al + Ti) ratio in the obtained tialite phase.
