Figure 1 (IMAGE) Institute for Basic Science Caption (top) Schematic diagram of a serially connected flexible tubular polymer electrolyte membrane fuel cells (t-PEMFC), and (bottom) (a-h) illustration of the simple fabrication process. (a) cut stainless-steel mesh, (b) is rolled into a conical shape and welded with a welding machine, (c) the anode gas diffusion layer (GDL) and catalyst-coated membrane (CCM) are rolled on the anode part of the cone, (d) heat is applied to bond the CCM, (e, f) the cathode GDL rolled onto the assembly, (g) the cathode electrode is inserted into the cell, and (h) heat is applied to seal the CCM junctions.
