Fabrication and Evaluation of Electrolyte-Supported Hollow Fiber Solid Oxide Fuel Cells
YSZ electrolyte-supported hollow-fiber SOFCs were successfully fabricated and their electrical and mechanical properties were investigated. The as-prepared hollow fiber SOFCs show a high mechanical strength of 149.0 MPa and 177.9 MPa before and after reduction by hydrogen gas, respectively. The open circuit voltage (OCV) values are greater than 1.0 V and the maximum power densities reach 146 mW cm-2 at 800°C, using wet H2 (～3% H2O) and static air as fuel and oxidant gas, respectively. As a result of high packing densities, this kind of YSZ electrolyte-supported hollow-fiber SOFCs has a high potential for practical applications.
