Many electrochemical conversion and storage technologies such as Li-ion and solid-state batteries, fuel cells and capacitors are being heavily investigated to decarbonise our environment . Fuel cells is one of the promising technologies and depending on the nature of the electrolyte used in the fuel cell there are various types of fuel cells: Solid Oxide Fuel Cell (SOFC), Molten Carbonate Fuel Cell (MCFC), Polymer Electrolyte (Proton Exchange) Membrane Fuel Cell (PEMFC), Phosphoric Acid Fuel Cell (PAFC), Direct Methanol Fuel Cell (DMFC) and Alkaline Fuel Cells (AFC). Broadly these fuel cell types can also be classified as high-temperature devices, such as SOFC and MCFC, and low-temperature devices such as PEMFC, PAFC, DMFC and AFC. The operating temperature of different fuel cell types tends to depend on the nature of the electrolyte being used and is also reflected in the applications of various fuel cell types. SOFCs, in particular, have attracted much attention in recent times. This increased interest in SOFCs stems from the fact that SOFCs have many advantages over other types of fuel cells. The flexibility of fuel, which allows the use of hydrogen, carbon dioxide, methane, and other hydrocarbons to power the cells is certainly a primary one. Further benefits include higher efficiency, a step towards a hydrogenbased economy, low emissions, relatively low cost and scalability, which allows the stacking of a required number of individual cells in series depending on the amounts of power needed in a particular device. It is in this context that SOFCs have assumed prime importance among the different types of fuel cells and we, therefore, believe that a concise review article briefly discussing promising materials families in the field would be relevant for researchers in the field. For comprehensive long reviews, we invite the reader to cited review articles here .
