The invention relates to tubular fuel cells and methods of making such fuel
cells. The inventive fuel cells include at least one fluid permeable
structure having a plurality of perforations or channels. The perforations
allow fluids, e.g., hydrogen or oxygen, to flow through the structure. The
inventive methods include forming at least one perforated structure and
forming the perforated structure into a tubular fuel cell or at least a
potential component of a tubular fuel cell.
