  • This paper presents the reversible electrolysis characteristics of a solid oxide fuel cell (SOFC) using a 10×10 cm2 anode supported planar cell with an active area of 81 cm2. In this work, current-voltage characteristic test and reversible electrolysis cycle test were carried out sequentially for 2,114 hours at a furnace temperature of 700℃. The current-voltage characteristics for reversible electrolysis mode was measured at a current of ±26.7 A under various H2O utilization conditions. The reversible electrolysis cycle was performed 50 times at a current of ±32.4 A. As a result, The performance degradation of SOEC mode was larger than that of SOFC mode.
