Abstract
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.
