    摘要: The invention describes a new design of ionomer membrane fuel cell stack comprising a multiplicity of stainless steel bipolar plates, electrodes, membranes and perimetrical sealing gaskets enclosed between compression plates. The novel design is directed to prevent the build up of metal ions in the membranes and the consequent voltage decay; for this purpose, the lateral migration inside the ionomer membranes of the metal ions contained in the cooling fluid is prevented.

    摘要: The invention relates to an anode comprising a titanium alloy substrate coated with noble metals by thermal decomposition of precursors thereof. The alloy of the substrate includes elements which can be oxidised during the thermal decomposition step, allowing electrical energy savings and a prolonged duration in industrial electrolytic processes. The anode of the invention is suitable for chlor-alkali electrolysis, allowing to produce chlorine with a lower oxygen content and a lower energy consumption than the anodes of the prior art.

    摘要: An electrolytic cell for the production of hydrogen peroxide with faradic efficiency and a method for the production of highly pure hydrogen peroxide with high faradic efficiency are disclosed. The cell is provided with a separator of high hydraulic permeability and is equipped with an oxygen-fed gas-diffusion cathode and with an anode activated with a catalyst for oxygen evolution. The high faradic efficiency of hydrogen peroxide generation is allowed by the dilution of product hydrogen peroxide by the anolyte crossing the permeable separator, and by keeping the operating temperature at values below 50° C.

    摘要: A membrane electrolysis cell comprising an anodic compartment and a cathodic compartment is described, wherein at least one of the two compartments contains an electrode fed with gas and a porous planar element is interposed between the membrane and the gas-fed electrode. A flow of chemically aggressive electrolyte crosses the porous planar element downwards under the effect of the gravity force. The planar element consists in a plastic element withstanding the aggressive operative conditions: The use of perfluorinated plastics such as ECTFE, PTEFE, FEP, PFA is preferred, even though they are strongly hydrophobic. When the gas-fed electrode is a cathode and the gas contains oxygen, the gas crosses the cathodic compartment upwardly so as to minimize the risk of hydrogen build up. The cell equipped with the oxygen cathode is particularly advantageous for the sodium chloride electrolysis.

    摘要: A membrane electrochemical cell, in particular a fuel cell, of an improved type comprising a multiplicity of cell elements, each element made up of bipolar plates, current collectors, electrodes and membranes, wherein the function of electric current transmission through the cell elements, the release of heat towards the outside environment, the distribution of electric current to the electrodes and membranes, the removal of heat from the electrodes and membranes and the distribution of the reactants and products are performed by distinct components, in particular bipolar plates for the first two and porous electroconductive collectors for the others. The bipolar plates may have flat surfaces without grooves and are preferably manufactured with aluminum, titanium or alloys thereof, through cheap mass productions techniques; the bipolar plates are used together with collectors provided with deformability, residual resiliency and high porosity. Said collectors advantageously act also as distributors of the gaseous reactants and of the products.
