| Research Abstract |
The chemical potential distribution of the reactive atomic species in high temperature electrochemical devices, such as the oxygen chemical potential in solid oxide fuel cells (SOFCs), was experimentally evaluated under device operating conditions. As results, we succeeded for the first time to clarify the oxygen potential distribution and the effective reaction area in the SOFC mixed-conducting porous cathode. Influences of such a chemical potential distribution on the device performance and durability were also investigated from the thermodynamic and kinetic points of view, taking the SOFC porous cathode as a model case.
