英文摘要	an anode-supported solid oxide fuel cell (sofc) with lanthanum-doped ceria (ldc) and strontium and magnesium doped lanthanum gallate (lsgm) bilayer electrolytes was fabricated and tested. the bilayer electrolyte thin film, consisting of a 25 mum thick ldc layer and a 75 mum thick lsgm layer, was prepared by a simple dry-pressing process. the two electrolyte layers were sintered together well, and no crack and peel-off at the interface were observed. an open-circuit potential of 1.02 v and a maximum power density of over 1.1 w/cm(2) was achieved with h-2 as fuel and air as oxidant at 800degreesc. the results show that the reactions between lsgm and anode materials were restrained by the ldc electrolyte layer, whereas the electronic conductivity of ceria-based electrolyte was blocked by the lsgm electrolyte layer.
