The overall electrolyte thickness ranged from 30 to 35μm, including a 3μm thick BCY layer. When the multilayered electrolyte cell was tested with hydrogen at the anode and air at the cathode in the temperature range of 500–700°C , it yielded open-circuit voltages (OCVs) of 846–1024mV, which were higher than the OCVs of 753–933mV obtained for a single-layered GDC electrolyte cell under the same conditions. The corresponding peak power densities reached 273, 731, and 1025mWcm^−2 at 500, 600, and 700°C , respectively. The multilayered electrolyte cell could also be applied to direct methane solid oxide fuel cell (SOFC) and single-chamber SOFC operating in a mixture of methane and air. These SOFCs yielded OCVs of 880–950mV and reasonable power densities without coking.}, pages = {A956--A960}, title = {Comparative Performance of Anode-Supported SOFCs Using a Thin Ce0.9Gd0.1O1.95 Electrolyte with an Incorporated BaCe0.8Y0.2O3 − α Layer in Hydrogen and Methane}, volume = {153}, year = {2006} }
