ABSTRACT:
In one embodiment of the present invention, a polygonal fuel cell comprises: a cathode layer having a tubular shape; a contact layer electrically coupled to and disposed on the cathode layer to leave an uncovered cathode surface portion; an electrolyte layer disposed on the uncovered cathode surface portion; and an anode layer electrically isolated from the contact layer, disposed on the electrolyte layer such that the polygonal fuel cell has a polygonal cross section to facilitate dense packing.
