In this study, we fabricated an anode-supported microtubular solid oxide fuel cell (SOFC) with the cell configuration (LSCF)– (CGO) cathode/CGO buffer layer/ (ScSZ) electrolyte/Ni–ScSZ anode. A power generation test of the SOFC was carried out at 0.1–0.7 MPa at . By using a wet gas mixture and air, the maximum power density of the microtubular cell was found to be (at , ) at atmospheric pressure (0.1 MPa). With increasing the operating pressure, the performance of the cell was improved, and the power density reached (at , ). It was confirmed by the current interruption method that both polarization and ohmic resistances decrease under a pressurized condition.
