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. %U http://www.benthamscience.com/open/toefj/articles/V001/7TOEFJ.htm
