摘要
With the aim to enhance the coking tolerance of traditional Ni-YSZ anode for direct-hydrocarbon solid oxide fuel cells, a new in-situ-grown Ni-Sr2WO5−δ cermet is proposed and evaluated as internal reforming catalyst. The new cermet of Sr2WO5−δ matrix with Ni nanoparticles is controllably obtained by in-situ reducing of double perovskite Sr2NiWO6 at 800 °C for 5 h. The single cell with the configuration of Ni-Sr2WO5−δ|Ni-YSZ|YSZ|LSM-YSZ exhibits a maximum power output of 270.0 mW cm−2 at 800 °C in wet methane. Just as promisingly, the single cell with Ni-Sr2WO5−δ works stably for 75 h at 700 °C, indicating the fact that the coking tolerance of Ni-YSZ anode can be promoted significantly. The results indicate that the new in-situ-grown Ni-Sr2WO5−δ cermet is a outstanding internal reforming catalyst for direct-hydrocarbon solid oxide fuel cells.
