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. La0.6Sr0.4Co0.2Fe0.8O3-delta and an ionic nanocomposite material as a core functional layer, sandwiched between n- and p conducting 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 mWcm(-2) at 550 degrees C in converting hydrogen fuel into electricity. (C) 2015 Elsevier Ltd. All rights reserved.
