“…However, high thermal expansion of NiO as compared to zirconia and large change in volume due to reduction of the anode material during cell operation makes it prone to electrolyte cracking in period of fabrication and cell operation. The problem of electrolyte cracking in order to maintain performance of cell can be sorted out by controlling the thickness of electrolyte, microstructure support and carefully selecting the content of NiO in composite of NiO-YSZ [68,102,103,109].…”

Today's world needs highly efficient systems that can fulfill the growing demand for energy. One of the promising solutions is the fuel cell. Solid oxide fuel cell (SOFC) is considered by many developed countries as an alternative solution of energy in near future. A lot of efforts have been made during last decade to make it commercial by reducing its cost and increasing its durability. Different materials, designs and fabrication technologies have been developed and tested to make it more cost effective and stable. This article is focused on the advancements made in the field of high temperature SOFC. High temperature SOFC does not need any precious catalyst for its operation, unlike in other types of fuel cell. Different conventional and innovative materials have been discussed along with properties and effects on the performance of SOFC's components (electrolyte anode, cathode, interconnect and sealing materials). Advancements made in the field of cell and stack design are also explored along with hurdles coming in their fabrication and performance. This article also gives an overview of methods required for the fabrication of different components of SOFC. The flexibility of SOFC in terms fuel has also been discussed. Performance of the SOFC with varying combination of electrolyte, anode, cathode and fuel is also described in this article.

“…Although the thickness and the microstructure of each component are variable, the ESC and the ASC used in this study represent typical examples of each cell. The typical microstructure of the anode-supported cell can be found elsewhere [23,24]. For the ASC and the MSC, two different bending tests were designed: one to induce tensile stress (convex electrolyte surface) and the other to induce compressive stress (concave electrolyte surface) on the electrolyte layer.…”

“…The barrier layer must prevent interdiffusion allowing electron and gas transport, have similar TEC to the other materials, and be stable and compatible with the relevant operating and processing conditions. Compositions including: La 0.6 Sr 0.2 Ca 0.2 CrO 3 [5], CeO 2 and Ce 0.8 Gd 0.2 O 2 [6] were found as effective diffusion barriers layers.…”
