Fabrication and Performance of Ni-YSZ Anode Supported Cell for Coal Derived Syngas Application by Tape Casting and Spin Coating
- West Virginia U., Morgantown WV
Ni-YSZ anode supported cell has been developed for direct utilization of coal derived syngas as fuel in the temperature range of 700-850° C. The porous Ni-YSZ anode substrate was prepared based on processes of slip casting and lamination of anode tape. Then thin-film YSZ electrolyte was deposited on pre-sintered anode substrate via a colloidal spin coating technique and an optimized final sintering route. Dense and crackfree YSZ electrolyte was successfully obtained after sintering at 1440C for 4hrs. Processing factors like pre-sintering of anode, solvent, coating cycles and sintering route on the final properties of YSZ film was studied. A power density of 0.62W/cm2 has been achieved for the anode supported cell tested in 97%H2/3%H2O at 800°C. EIS test results indicated the cell performance was essentially influenced by interfacial resistance and charge transfer process.
