MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517091096 A) filed by Robert Bosch Gmbh, Stuttgart, Germany, on Sept. 23, for 'electrochemical cell and cell stack.'
Inventor(s) include Prinsen, Lucas; and Van Laerhoven, Joost.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to an electrochemical cell (1), in particular a fuel cell or an electrolysis cell, having a membrane (2) with an active surface and an edge region enclosing the active surface, wherein a gas and/or liquid transporting layer (3) lies against both sides of the active surface of the membrane (2) and the edge region is enclosed at least along one side of the active surface by a frame structure (4) adjacent to the gas and/or liquid transporting layers (3), and wherein at least one elongated opening serving as a media channel (5) is formed in the frame structure (4) and is divided by at least one crosspiece (6) into multiple individual openings (5.1, 5.2,... 5.n). According to the invention, the frame structure (4) has a depression (7), which extends over the entire length (L) of the media channel (5) and connects the individual openings (5.1, 5.2,... 5.n) to one another and also to the adjacent gas and/or liquid transporting layer (3). It is alternatively proposed that the frame structure (4) has connecting channels (8), which respectively extend from an individual opening (5.1, 5.2,... 5.n) to the adjacent gas and/or liquid transporting layer (3) in a fan-like arrangement. The invention also relates to a cell stack, in particular a fuel-cell stack or an electrolysis-cell stack, with at least one electrochemical cell (1) according to the invention."
