Abstract
Doping a LaMnO<sub>3</sub> cathode with the Ca element produces a La<sub>0.5</sub>Ca<sub>0.5</sub>MnO<sub>3−δ</sub> cathode, which shows high performance for proton-conducting solid oxide fuel cells, surpassing all similar cells, although the low basicity of Ca makes it an inappropriate doping element in traditional thinking.
