Design and Fabrication of a 600W Anode Supported Flat Tubular SOFC Stack

A 600W anode supported flat tubular SOFC stack is designed and fabricated. FeCrAl alloy is applied as metallic cassette. Ag-Cu serve as seal to the anode and metallic cassette and electrical connect to anode. After tested for 1000 hours, the jointing of FeCrAl, Ag-Cu braze and anode shows good stability. With cells of Ni-YSZ/YSZ/LSM-YSZ, a maximum output of 614W and an average power density of 213mw/cm2 are obtained in this stack configuration. The fuel utilization efficiency is high as 51%.
