Protonlederande refers to the property of a material to conduct protons. This means that protons, which are positively charged subatomic particles found in the nucleus of an atom, are able to move through the material. This movement of protons constitutes an electric current.

Proton conductivity is distinct from electronic conductivity, where electrons are the charge carriers. Materials that exhibit proton conductivity are often referred to as proton conductors or solid proton electrolytes. These materials are typically solid-state and are of interest in various electrochemical applications.

Key characteristics of proton conductor materials include their ability to transport protons at specific temperatures and under certain humidity conditions. The mechanism of proton transport can vary depending on the material's structure and composition, but often involves the movement of protons through hydrogen-bonded networks or vacancies within the material's lattice.

Applications where proton conductivity is important include fuel cells, particularly proton exchange membrane (PEM) fuel cells. In these devices, a proton conductor acts as an electrolyte, allowing protons generated at the anode to migrate to the cathode, where they combine with oxygen to produce electricity and water. Other potential applications include sensors, electrocatalytic reactors, and hydrogen separation membranes. The development of efficient and stable proton conductor materials is crucial for advancing these technologies.
