Performance Improvement of Ni-YSZ-Based Solid Oxide Fuel Cell with the Anode Functional Layer Synthesized by Co-Precipitation Method

The nanopowder for the Ni-YSZ anode functional layer (AFL) was prepared by ammonium carbonate co-precipitation method. The electrolyte thickness of the Ni-YSZ-based cell with the anode functional layer was about 16 μm. The anode functional layer coated 2times by dip-coating method was 18 μm in thickness. Compared to the Ni-YSZ cell without AFL, the cell performance was greatly increased in the cell with AFL, showing above 0.6 Wcm-2 at 800 °C. This result exceeds 0.35 W cm-2 of the cell without AFL at the same temperature by approximately two times. Thus, the anode functional layer synthesized by co-precipitation method can be a promise for the performance improvement of YSZ-based solid oxide fuel cells in intermediate temperature range.
