要約(英語): The performance of surface ionic conduction single chamber fuel cell (SIC-SCFC) prepared by the sol gel method was studied on electric characteristics due to the differences of the operating temperature and humidity, the electrode distance and electrolyte film depth, and multiple cells with the series and parallel connections. The SIC-SCFC was arranged the both anode of Pt and cathode of Au on the boehmite electrolyte. The open circuit voltage (OCV) of single cell achieved a maximum of 530mV in the dry gas mixtures of O2/H2=50% in room temperature operation, and but it became decrease as over 60%. The OCV was maintained the constant value between operating temperatures of 30℃ to 80℃, and but it was decreased sharply at over 90℃ because a humidity on the cell became lower as increasing operating temperature. Then, the cell property was improved to 120℃ by adding to the humidity of 70% using a humidifier. The electrode distance and the electrolyte film depth of SIC-SCFC found to be contributed to the reductions of the cell resistance and the surface roughness on the electrode, respectively. Moreover, the power property of SIC-SCFC was significantly improved by cell stacks comprised of the series or parallel connection of a cell.
