Perovskite oxide protons refers to materials with the perovskite crystal structure that are capable of transporting protons. The general formula for a perovskite oxide is ABO3, where A and B are metal cations and O is oxygen. In the context of proton conductivity, some of these oxides can incorporate hydrogen ions (protons) into their structure, often through doping with elements like yttrium or samarium, or by substituting oxygen with hydroxyl groups.

Proton transport in these materials typically occurs via a hopping mechanism, where protons move from one oxygen atom to an adjacent one through defects or interstitial sites within the crystal lattice. This process is highly dependent on temperature and the presence of water, which can act as a proton source and facilitate transport.

Perovskite oxide protons are of significant interest for their potential applications in electrochemical devices, particularly in solid oxide fuel cells (SOFCs). In SOFCs, these materials can function as proton-conducting electrolytes, allowing for lower operating temperatures compared to traditional oxygen-ion conducting electrolytes. This can lead to improved efficiency and reduced material degradation. Other potential applications include hydrogen sensors and membranes for hydrogen separation. Research in this area focuses on improving conductivity, stability at high temperatures, and reducing manufacturing costs.
