Influence of intrinsic spin ordering in La_0.6Sr_0.4Co_0.8Fe_0.2O_3-δ and Ba_0.6Sr_0.4Co_0.8Fe_0.2O_3-δ towards electrocatalysis of oxygen redox reaction in solid oxide cell.

ABSTRACT: The redox reaction of oxygen (OER & ORR) forms the rate determining step of important processes like cellular respiration and water splitting. Being a spin relaxed process governed by quantum spin exchange interaction, QSEI (the ground triplet state in O₂ is associated with singlet oxygen in H₂O/OH^-), its kinetics is sluggish and requires inclusion of selective catalyst. Functionality and sustainability of solid oxide cell involving fuel cell (FC) and electrolyzer cell (EC) are also controlled by ORR (oxygen redox reaction) and OER (oxygen evolution reaction). We suggest that, presence of inherent spin polarization within La_0.6Sr_0.4Co_0.8Fe_0.2O_3-δ (LSCF6482) (15.86 emu g^-1) and Ba₀
