摘要
En 中文
Solid-oxide fuel cell power densities typically drop rapidly as the operating temperature is decreased, due to electrolyte ohmic losses and/or electrode overpotentials. In this paper, we describe fuel cells utilizing 8 mu m thick yttria-stabilized zirconia (YSZ) electrolytes to provide low ohmic loss. Adding thin porous yttria doped ceria (YDC) layers on either side of the YSZ yielded much-reduced interfacial resistances at both the LSM Cathodes and Ni-YSZ anodes. The cells provide higher power densities than previously reported below 700 degrees C, e.g. 300 and 480 mW cm(-2) at 600 and 650 degrees C, respectively (measured in 97%H-2 + 3%H2O and air), and also provide high power densities at higher temperatures, e.g. 760 mW cm(-2) at 750 degrees C.
