1. A sub-fuel cell comprising:

  • a plurality of unit cells, comprising anode unit cells and cathode unit cells;

    a proton conducting polymer membrane, the anode unit cells being placed on one side of the membrane and the cathode unit cells being placed on the other side of the membrane opposite the anode unit cells;

    a thin polymer film having openings for the anode and cathode unit cells and electrical leads, the thin polymer film being placed on each side of the proton conducting polymer membrane and around the anode unit cells and the cathode unit cells to collect electric current from each unit cell; and

    two fuel-feed plates having spaces corresponding to the anode unit cells and the cathode unit cells and interconnecting channels for supplying fuel to the anode unit cells and the cathode unit cells, one fuel-feed plate being placed on the side of the thin polymer film having the anode unit cells and one fuel-feed plate being placed on the side of the thin polymer film having the cathode unit cells.
