Direct utilization of methane in conventional tubular solid oxide fuel cells (SOFCs) with a Ni-YSZ anode support was proposed using MoO2 as a partial oxidation catalyst for methane reforming at the cell inlet. A promising stability was achieved for a continuous operation in a mixture of methane and air (1, 1.5) for > 150 h under a load voltage of 0.7 V at 750 °C. The addition of the MoO2 catalyst at the anode inlet made tubular SOFCs with the conventional Ni-YSZ anode an efficient and practically promising candidate for direct hydrocarbon utilization.

二氧化钼作为管状固体氧化物燃料电池中甲烷直接利用的替代催化剂

有人建议使用MoO 2作为部分氧化催化剂,在带有Ni-YSZ阳极载体的常规管状固体氧化物燃料电池(SOFC)中直接使用甲烷,以在电池进口处进行甲烷重整。在750°C的0.7 V负载电压下,在甲烷和空气(1,1.5)的混合物中连续运行> 150小时可获得稳定的稳定性。在阳极入口处添加MoO 2催化剂使得具有常规Ni-YSZ阳极的管状SOFC成为直接利用碳氢化合物的有效且在实践中很有希望的候选者。
