Sulfur and Carbon Resistance of Ni-GDC and Ni-YSZ Anode

摘要

Successful implementation of fuel cell technology in the energy supply chain will largely depend on the design of cost efficient and reliable fuel cell systems. This paper discusses the robustness of the solid oxide fuel cell anode to survive malfunctioning of a sulfur cleaning unit, leading to temporary sulfur breakthrough, and malfunctioning of a steam supply unit, leading to temporarily increased carbon activity. Results obtained on SOFC single cells with Ni-GDC and Ni-YSZ anode operated with hydrogen, syngas and methane are shown, and the most likely deactivation mechanisms are discussed.
