A study of short stack with large area solid oxide fuel cells by aqueous tape casting

摘要

Solid oxide fuel cells (SOFC) are very attractive for their high energy conversion efficiency and pollution-free characters. A 10 cm * 10 cm fuel electrode-supported solid oxide cell with NiO/Zr0.92Y0.08O2-delta fuel electrode, Zr0.92Y0.08O2-delta electrolyte and La0.6Sr0.4Co0.2Fe0.8O3+delta air electrode has been used, which is fabricated by aqueous-based tape casting in conjunction with co-sintering. In this article, a short stack test structure of large area single cell has been designed and shown, and the maximum power density is 265.8 mW cm(-2) at 800 degrees C with humidified H-2 as the fuel and air as the oxidant.
