Abstract

The electrochemical performance and stability of the planar metal supported solid oxide fuel cells (MS-SOFC) with two different electrocatalytically active materials, namely, Ni:GDC and Ru:GDC were investigated. Ru:GDC with an ASR of 0.322 Ωcm² performed better than Ni:GDC with an ASR of 0.453 Ωcm² at 650oC. The performance of the Ru:GDC infiltrated MS-SOFC is the best measured so far on planar MS-SOFCs. It was observed that the stability of both the electrocatalytically active materials is relatively poor. Microstructure of the anode functional layer appeared to be dense up on the examination. Further optimization of microstructure, electrocatalyst amount and electrocatalyst integration process can improve the long-term stability in particular and electrochemical performance in general.
