Improved Performance and Durability of Anode Supported SOFC Operating on Biogas
Performance curves for both Sn-doped Ni-YSZ and un-doped Ni-YSZ single cells are presented in Fig.1. The cell tests were carried out at 750 o C under dry hydrogen flowing at 7mL/min Helium and 21mL/min H 2 followed by biogas flowing at 7mL/min CO 2 : 14mL/min CH 4 : 7 mL/min He with the cathode sid...

| Summary: | Performance curves for both Sn-doped Ni-YSZ and un-doped Ni-YSZ single cells are presented in Fig.1. The cell tests were carried out at 750

: 7 mL/min He with the cathode side open to ambient air.
The cells were allowed to reduce under H

for a minimum of 3hrs in OCV mode before any initial data was obtained. Operation on hydrogen was run for 26 hours to stabilize cell performance before the fuel was switched to biogas. After stabilization on hydrogen the Sn-doped Ni-YSZ gave 390mA/cm

at 0.7V compared to the un-doped Ni-YSZ cell which gave 100mA/cm

at 0.7V. |
