Abstract:
1. A solid oxide fuel cell, comprising: a metal frame; a porous metal substrate disposed in the metal frame; an anode layer disposed on the porous metal substrate, the anode layer being porous and nano-structured; an electrolyte layer disposed on the anode layer, the electrolyte layer being dense and gas-tight; a cathode interlayer disposed on the electrolyte layer, the cathode interlayer being porous, nanostructured or micron structured; and a cathode current collecting layer disposed on the cathode interlayer; a protection layer coated on the metal frame to prevent chromium pollution on the cathode interlayer and the cathode current collecting layer; wherein the anode layer comprises a plurality of anode electron-conducting nano-particles and a plurality of anode ion-conducting nano-particles arranged to form a plurality of anode nano-pores between the anode electron-conducting nano-particles and the anode ion-conducting nano-particles, and the cathode interlayer comprises a plurality of cathode electron-conducting particles and a plurality of cathode ion-conducting nano-particles arranged to form a plurality of cathode pores between the cathode electron-conducting particles and the cathode ion-conducting nano-particles.
