High performance, coking-resistant and sulfur-tolerant anode for solid oxide fuel cell

摘要

Solid oxide fuel cell can efficiently generate electricity using methane fuel; however, methane cracking at high temperature often results in carbon deposition that leads to degradation of power output. Here, metal-oxide interface is in stiu constructed in LSCM anode to enhance methane oxidation. The anchored interface demonstrated exceptionally high resistance to carbon coking and sulfur poisoning. The peak power density with Cu0.5Fe0.5-LSCM anode is as high as 0.64 W cm(-2 )using methane fuel at 850 degrees C. Electrochemical measurement shows a stable power output under current density of 0.4 A cm(-2) using methane fuel even after 10 redox cycles at 850 degrees C.
