Abstract

A power generation system consisting of an intermediate-temperature solid oxide fuel cell (IT-SOFC) and an external reformer for biogas is developed, and its performance is investigated for advanced use of effective biogas. The IT-SOFC is fueled with syngas produced via biogas reforming, and is successfully operated at 600 and 700 °C using Ni_0.8Cu_0.2 alloy/gadolinia-doped ceria electrolyte (Ni_0.8Cu_0.2/GDC) cermet anodes and a LaAlO₃ supported-Ni (Ni/LaAlO₃) catalyst. The Ni/LaAlO₃ catalyst stably exhibits high reforming performance for effective biogas at 800 °C for 27 h, and carbon deposition on the catalyst is prevented. The electrochemical performance of the Ni_0.8Cu_0.2/GDC cermet anode using syngas fuel possessing a H₂:CO ratio of approximately 3:1 is comparable to the performance achieved with H₂ fuel; the anode remains stable after 24 h of operation at 700 °C without interruption and is unaffected by carbon deposition.
