| Outline of Final Research Achievements |
Several brownmillerite- and perovskite-type proton conductors, which show unique proton and electrical conductivities, have been successfully synthesized by a solid-state reaction chemistry route.
The conventional lattice-defect-type perovskite compounds show the proton conductivities by supplying hydrogen gas and steam for the hydrogen sources. However, these samples showed the high proton conductivities in intermediate-temperatures without the hydrogen sources.It revealed that the three kinds of water absorption in a perovskite-phase cause for the high proton conductivities in intermediate-temperature by analysis of the chemical composition.
