A solid oxide fuel cell comprises a plurality of tubes, each having an anode, electrolyte and cathode. Anode and cathode current collectors are mounted on the tubes. The anode current collector electrically connects to the anode and can have a contact with the anode. The cathode current collector electrically connects to the cathode and can have a contact with the cathode. An electrically conductive sealant may be positioned between the anode of one tube and the cathode current collector of another tube.
