YCuO2 is a copper-yttrium oxide ceramic compound belonging to the family of mixed-valence metal oxides with semiconductor properties. This material is primarily investigated in research settings for applications requiring oxygen-ion conductivity and thermal stability, particularly as a candidate electrolyte or electrode material in solid-oxide fuel cells (SOFCs) and related electrochemical devices. YCuO2 is notable for its potential to operate at intermediate temperatures while maintaining structural integrity, offering an alternative pathway to conventional yttria-stabilized zirconia (YSZ) in energy conversion systems where cost and material availability are considerations.
