%X Co-doping of yttrium doped mixed barium cerate/zirconate perovskite (BCZY) with small amounts of Pr (BCZYP) substantially increases electrical conductivity while retaining structural and chemical stability. BCZYP is predominantly a proton conductor at temperatures up to 600-650ˇăC, whereas it is a mixed proton/oxide ion/electron conductor at higher temperatures. The co-doped BCZYP perovskite can be useful for applications requiring proton conduction at intermediate temperatures.
