Solid oxide electrochemical devices, such as fuel cells and electrolyzers, are the subject of research due to their wide range applications. Electrochemical devices with symmetric, that is, chemically identical electrodes, have been actively investigated in recent years. This design can significantly reduce time cost fabrication improve start‐up by eliminating electrode reduction step. A serious challenge development symmetrical is find materials equally effective both air (hydrogen, methane, carbon monoxide, etc.) atmospheres. One material Sr 2 Fe 1.5 Mo 0.5 O 6- δ (SFM). SFM exhibits satisfactory electrical conductivity activity, high stability oxidizing reducing atmospheres, under redox cycling a gas environment. paper presents, for first time, results studies which fraction strontium cations replaced praseodymium. The praseodymium cation mainly interesting because it has two oxidation states, +3 +4, positively influence transport properties SFM, activity various mixtures.
