1. improve a method for high pressure electrolysis cell efficiency, described high pressure electrolysis cell has anode and negative electrode, which defines the inside between them, and wherein said anode has internal surface;

  • Negative electrode is connected in described anode at least partly, and described negative electrode has outside surface;

    Described electrolyzer also comprises direct supply, and it has the positive terminal being electrically connected to described anode, and is electrically connected to the negative terminal of described negative electrode;

    Limit inner between the described outside surface of described negative electrode and the described internal surface of described anode;

    Be connected to the electrolytic bath membrane in described inside, described inside is divided into anolyte compartment and cathode compartment by described electrolytic bath membrane, and the volume of described anolyte compartment is greater than the volume of described cathode compartment;

    And liquid electrolyte, it is comprised in described inside;

    Described method comprises;

    When described high pressure electrolysis cell work, reduce anodic current density and reduce anodic overvoltage;

    WithWhen high pressure alkalescence electric tank working, reduce to penetrate through from cathode compartment the amounts of hydrogen that electrolytic bath membrane enters anolyte compartment.
