The study of Au/MoS2 anode catalyst for solid oxide fuel cell (SOFC) using H2S-containing syngas fuel

Au/MoS2 is a promising anode catalyst for conversion of all components of H2S-containing syngas in solid oxide fuel cell (SOFC). MoS2-supported nano-Au particles have catalytic activity for conversion of CO when syngas is used as fuel in SOFC systems, thus preventing poisoning of MoS2 active sites by CO. In contrast to use of MoS2 as anode catalyst, performance of Au/MoS2 anode catalyst improves when CO is present in the feed. Current density over 600 mA cm−2 and maximum power density over 70 mW cm−2 were obtained at 900 °C, showing that Au/MoS2 could be potentially used as sulfur-tolerant catalyst in fuel cell applications.
