Abstract: A gas diffusion electrode includes a carbon fiber tube, a support layer, and a catalyst layer. The carbon fiber tube is straight and functions as a substrate. The support layer includes a carbon black-polytetrafluoroethylene (PTFE) coating, and is disposed on the substrate. The catalyst layer includes carbon black, anhydrous ethanol, and PTFE, and is disposed on the support layer. The gas diffusion electrode has a diameter of 3-20 mm and a length of 50-500 mm.
