Patent ID: 7659025

Claim:
A method for manufacturing a solid oxide fuel cell, the method comprising: forming a tubular anode comprising an electrolyte substance and an oxide of an electrochemically active metallic substance without a distinct pore forming substance; sintering the tubular anode; forming an electrolyte onto the sintered anode; forming a cathode onto the electrolyte; and after forming the electrolyte and the cathode, reducing the oxide of the electrochemically active metallic substance in the sintered anode to form pores in the anode, the anode comprising, after reducing the oxide, an electrochemically active metallic substance and an electrolyte substance without a distinct pore forming substance, the electrochemically active metallic substance consisting essentially of reduced metal oxide, wherein a thickness of the anode comprises over 50% of a total thickness of the anode, the electrolyte, and the cathode.
