1. a hydrogen-oxygen proton exchange membrane fuel cell is characterized in that with the cylindrical membrane electrode of band tapering:

  • from inside to outside be followed successively by anode, composite membrane, negative electrode respectively and form, what contact with hydrogen is anode, and what contact with air is negative electrode;

    Composite membrane is made up of proton exchange membrane, Catalytic Layer, diffusion layer, and there is out splice going splice at the positive plate place, and the sealing ring with anode out splice going splice and composite membrane and cathode isolation is set at anode out splice going splice place, and the bottom of negative electrode is the negative electrode out splice going splice;

    Anode is tapered, and composite membrane is the taper with the anode taper fit, and negative electrode is a hollow tube, and the outer surface of negative electrode hollow tube is cylindrical, and the endoporus of negative electrode hollow tube is the taper hole form identical with the negative electrode tapering.
