Patent number: 8591719Abstract: 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.Type: GrantFiled: March 20, 2009Date of Patent: November 26, 2013Assignee: Industrie de Nora S.p.A.Inventor: Giuseppe Faita

Patent number: 7670472Abstract: 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.Type: GrantFiled: November 12, 2002Date of Patent: March 2, 2010Assignee: Uhdenora Technologies S.R.L.Inventors: Giuseppe Faita, Fulvio Federico

Patent number: 7282284Abstract: The invention describes a method and the relevant devices for permitting an operation stable with time of a stack of membrane fuel cells fed with air and a gas containing hydrogen and at least 100 ppm of carbon monoxide, characterised in that it provides for an oxidising condition at the anodes of said cells in a self-adjusting continuous way or sequentially discontinuous way. Different embodiments of the invention are illustrated wherein the oxidising condition is obtained by adding to the gas containing hydrogen and carbon monoxide, oxygen produced in an electrolysis cell integrated to the fuel cell stack, or by flowing air through porous areas obtained in the bipolar plates or by resorting to high gas diffusion rate membranes, wherein the air flow rate is regulated in both cases by adjusting the pressure differential existing between air and the gas containing hydrogen and carbon monoxide.Type: GrantFiled: March 6, 2002Date of Patent: October 16, 2007Assignee: Nuvera Fuel Cells Europe S.R.L.Inventors: Giuseppe Faita, Enrico Ramunni
