Abstract：A novel fuel-to-electricity conversion technology resembling a fuel cell has been developed
based on the perovskite solar cell principle using a perovskite, e.g. La0.6Sr0.4Co0.2Fe0.8O3δ and
an ionic nanocomposite material as a core functional layer, sandwiched between n- and pconducting
layers. The conversion process makes use of semiconductor energy bands and
junctions properties. The physical properties of the junction and alignment of the semiconductor
energy band allow for direct ion transport and prevent internal electronic shortcircuiting,
while at the same time avoiding losses at distinct electrolyte/electrode interfaces
typical to conventional fuel cells. The new device achieved a stable power output of
1080 mWcm2 at 550 1C in converting hydrogen fuel into electricity
