MUMBAI, India, July 5 -- Intellectual Property India has published a patent application (202517058632 A) filed by Robert Bosch Gmbh, Stuttgart, Germany, on June 18, for 'method for regenerating an electrolyser.'

Inventor(s) include Steiner, Dietmar; and Hackenberg, Juergen.

The application for the patent was published on July 4, under issue no. 27/2025.

According to the abstract released by the Intellectual Property India: "The invention relates to a method for regenerating an electrolyser which is designed for producing hydrogen and oxygen with the aid of electrical energy and which comprises an electrolysis cell (1), the electrolysis cell (1) having a cathode chamber (2) and an anode chamber (3) which are separated from one another by a selectively permeable membrane (6). The membrane (6) is coated on the side facing the cathode chamber (2) with a cathode electrode (7) and on the side facing the anode chamber (3) with an anode electrode (8), between which an electrical voltage is applied during operation of the electrolyser, the anode electrode (8) consisting of a porous material and the anode chamber (3) being filled with water or an aqueous electrolyte solution during operation of the electrolyser. To carry out the method, the following steps are performed: - lowering the electrical voltage between the anode electrode (8) and the cathode electrode (7) to 0 V; - lowering the pressure in the anode chamber (3) to less than 2 bar (0.2 MPa); - removing the water or the aqueous electrolyte solution from the anode chamber (3); - introducing hydrogen gas into the anode chamber (3); - refilling the anode chamber (3) with water or with aqueous electrolyte solution."

The patent application was internationally filed on Nov. 22, 2023, under International application No.PCT/EP2023/082698.
