| Outline of Final Research Achievements |
In order to clarify the relation between the proton transport property and the potential gradient into oxide, the conductivity, and the electromotive force, the performance of electrochemical cell such as fuel cell and steam electrolysis cell were measured for proton-conducting oxide at various condition. The high proton conductivity was observed under high water vapor pressure. The electromotive force of gas concentration cell using proton-conducting oxide as electrolyte increased due to temperate gradient. This suggest to inhibit the influence of the hole conduction by the potential control. The fuel cell performance of bi-layered proton-conducting oxide was examined at 1073 K. The open circuit voltage increased but the improvement of the power density was not observed due to bi-layer structure.
