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.

“…Table 4 compares the anode failure probability and the compressive stress strength ratios of the electrolyte and cathode for the anode-, cathode-, and electrolyte-supported cell designs. The layer thicknesses and the electrode compositions are from the relevant experiments [31][32][33]. However, due to various theoretical and experimental uncertainties, the results in Table 4 are most meaningful for discussing the qualitative trends.…”

Mechanical damage is a major factor limiting the long-term stability of solid oxide fuel cells (SOFCs). Here, the mechanical stability of planar SOFCs consisting of Ni-YSZ anode/YSZ electrolyte/LSM-YSZ cathode (Ni=Nickel, YSZ=yttria-stabilized zirconia, LSM=lanthanum strontium manganite) is analyzed by a structural mechanics model with composition dependent mechanical properties.Influencing factors considered include: the Ni and LSM volume fractions, the thicknesses of anode, cathode and electrolyte layers, and the cell types of anode-, cathode-, and electrolyte-supported designs. It is found that (i) the anode failure probability increases with the Ni content. However, SOFCs remain mechanically safe if the Ni volume fraction is below 65%.(ii) An LSM volume fraction of over 40% is required to maintain the mechanical integrity of cathode. (iii) For an anode-supported cell with a 20 µm thick electrolyte, the anode thickness should be more than 0.5 mm to be mechanically stable. (iv) The anode-supported cell is found to be mechanically safer than that of the electrolyte-supported cell.

“…It is well known that SOFC offer many advantages such as high energy efficiency (above 85%) via the combination of the production of heat and electricity, and flexibility in the used fuels (natural gas, hydrogen, biofuels or syngas) through the internal reforming capability of these systems [1,2]. Among the different proposed solutions, solid oxide fuel cells (SOFC) could be an attractive complementary possibility.…”

This work reports a proof of concept to obtain a shaped porous metallic alloy by the reduction at low temperature of an oxide precursor shaped at high temperature. A mixed cations oxide selected for potential applications in solid oxide fuel cells (SOFCs), is prepared using Pechini's polymer route and consolidated using the spark plasma sintering (SPS) technique at temperature in the 900 °C – 1,100 °C range. A pellet of pure AB2O4 spinel‐like structure with 10% of open porosity is obtained. The reduction of this pellet under H2 flow at low temperature (800 °C) allows obtaining a highly porous (48%) metallic pellet which meets all necessary characteristics to be used as mechanical support for the third generation of SOFC (3G‐SOFC). The use of oxide precursors widen the accessible temperature range allowing the possibility to stack in one step an oxide precursor of the 3G‐SOFC with full densification of the electrolyte. This proof of concept opens the way to the easy and cheap “one step” building of an oxide precursor of 3G‐SOFC which will be in situ activated during the warming up of the cell.
