However, LSM- and LSCF-based perovskites are still the best materials of choice for the cathodes of SOFC despite new advance materials have been introduced.
LSM-based materials can be synthesised with other materials to form a dual composite material by infiltration and impregnation of catalytically active materials [2].
This cathode can be achieved through the proper selection of materials.

The normative pressure arises from customers demanding ecologically sustainable vehicles and being willing to pay extra to get renewable materials in their cars [61, 67].  
Likewise, green technology is related to production technology, such as cleanups for reducing pollution and the materials used to produce environmentally friendly cars [26].
