A process for manufacturing a solid oxide fuel cell involves 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 substance in the sintered anode to form pores in
the anode.
