ABSTRACT:
A pre-spiral bundle for making a spiral wrapped cylindrical fuel cell and cylindrical fuel cells made using the pre-spiral bundle. The pre-spiral bundle comprises a sleeve defining a hydrogen flowpath. The sleeve comprises a proton exchange membrane encapsulating a substantially planar anode in ionic communication with a catalytically effective amount of a noble metal catalyst. A first hydrogen inlet comprises a first edge of the sleeve and a second hydrogen inlet comprises an opposed, substantially parallel edge of the sleeve. The hydrogen flowpath is defined by the anode. A cylindrical fuel cell is made by abutting a flexible, porous cathode to the sleeve in ionic communication with a noble metal catalyst and wrapping the sleeve and the cathode around one of the hydrogen inlets.
