Electrolyte is located between the cathode and anode of a proton-conducting solid-oxide fuel cell, and thus links two electrodes, thereby enabling protons to be transferred. Therefore, the performance of the proton-conducting solid-oxide fuel cell (e.g., efficiency of power generation) is highly dependent on the electrolyte. According to current literature, using a dopant of low-valence elements (e.g., potassium, yttrium, gadolinium, and Indium) increases oxygen vacancies in solid-oxide electrolyte and effectively improves electrolyte conductivity. However, employing a dopant containing excessive concentrations of low-valence elements causes lattice distortion, which reduces the stability of the lattice or microstructure, thereby decreasing electrolyte conductivity.
