Abstract

Perovskite systems have attracted considerable interest for fuel cell/electrolyser applications. Here we show that phosphate can be incorporated into the mixed Mn/Fe system Sr₂MnFeO_6-δ. In all cases, the conductivity was shown to increase for low doping levels (≤10 % phosphate incorporation) with a subsequent decrease for higher doping levels, attributed to the presence of Sr₃(PO₄)₂ impurity as the solubility limit is exceeded. The work further illustrates that phosphate can be doped into perovskite systems, highlighting this doping approach as an alternative strategy to modify the structure and properties.
