Unveiling distribution of protons and oxygen vacancies in perovskite-type proton conductors

Solid oxide fuel cells (SOFC), recently used as a power source for households in Japan, have several drawbacks such as high-cost, material degradation and long start-up time derived from high operating temperatures up to 750°C. Lowering the operating temperature to an "intermediate" range of 300-500°C would, in effect, enable the use of low-cost materials and allow for a quicker start-up which, in turn, could lead to wider commercial use and application to a mobile power source.
