TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The porous conducting substrate is made of carbon or titanium material.Preferred Components: The particles of the metallic catalyst include of platinum (Pt) series metals, e.g., Pt, iridium or ruthenium. The catalyst layer is formed out of particles of different metals in such a manner that a sublayer out of particles of one metal alternates with a sublayer out of particles of another metal thus producing a multilayer catalyst.Preferred Composition: The metallic catalyst includes Pt and lead in the proportion of 1:5 to 1:15 (by weight). The complexes of catalytic metals in aqueous solution with concentrations of 10-4-5:10-4 mol/l.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The layer of ion-exchange membrane is made of solid polymer electrolyte comprising Nafion carbon tetrafluoride or MF-4SK.Preferred Property: The layer of the polymer ion-exchange membrane has a thickness of 10-30 microns.Preferred Component: A colloidal solution of polymer Nafion is used as polymer and the drying of the colloid solution layer of the polymer is performed at 30-100 degreesC for 0.8-1.5 hours.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: The layer of polymer ion-exchange membrane with channel-clustered structure is produced by applying a layer of the colloid solution of an oligomer in an organic solvent onto the porous conducting substrate and then heating it up until a polymer layer of ion-exchange membrane with a channel-clustered structure is formed. A colloidal solution of oligomer Nafion in isopropanol with the concentration of 8-12 wt.% is used and the substrate with the applied colloid solution of the oligomer is heated up to 70-100 degreesC for 1-1.5 hours. The ion exchange during the formation of a catalyst layer is performed by holding the substrate with the applied membrane layer in an aqueous solution of a salt or a complex compound of a metal which was selected as a catalyst. In case the cations of Pt, Ru and Ir are introduced for forming of catalyst layer, Pt, Ru or Ir is electrochemically reduced at the current density of 0.5-1 A/cm2 at 70-90 degreesC for 1-2 hours. The electrode with a layer of ion-exchange polymer is washed in water before to the electrochemical reduction. The electrochemical reduction is carried out in an electrolysis bath where the electrolyte does not contain cations of the catalytic metal. It is carried out in bath containing sulfuric acid with a concentration of 0.05-2 moles. It also carried out at a difference of potentials that is less than the difference of potentials that leads to the hydrogen release. When the substrate has hydrophobic properties, the electrochemical reduction is carried out using direct or pulse current with the cathodic current density of 15-200 mA/cm2 at 20-95 degreesC for 1-2 hours. The cations formed as a result of dissociation of an aqueous solution of lead (II) nitrate or lead (II) acetate are used as cations, and electrochemical reduction is carried out with current density of 10-300 mA/cm2 and at 20-95degreesC for 1-2 hours.Preferred Components: The anode and cathode have identical catalyst layers.Preferred Property: The separating membrane has a thickness which does not exceed 100 microns.
