Patent ID: 8715885

Claim:
A fuel cell comprising: a porous anode electrode; a dense non-porous electrolyte; and a porous cathode electrode; wherein the anode electrode includes a first member and a plurality of parallel plate members extending from the first member, the first member forming a conduit for the flow of a fuel, and a first end of the first member is sealed by an end cap or electrolyte, the cathode electrode includes a second member and a plurality of parallel plate members extending from the second member, the second member forming a conduit for the flow of an oxidant, and a first end of the second member is sealed by an end cap or an electrolyte, the plate members of the cathode electrode interdigitate with the plate members of the anode electrode, electrolyte fills the spaces between the first member and the second member, and between the parallel plate members of the anode electrode and the parallel plate members of the cathode electrode, and the first member and the second member are hollow tubes, and either the first member is positioned around the second member or the second member is positioned around the first member.
