A process for manufacturing a flow guide for an electrochemical reactor, including providing a substrate; on a first face of the substrate, printing a layer of electrically conductive ink by applying a shear stress to this layer, the viscosity of the printed ink being comprised between 70 and 500 Pa&#xb7;s for a shear rate of 0.1 s, and the viscosity of the printed ink being comprised between 2.5 and 7 Pa&#xb7;s for a shear rate of 100 s, the layer of ink being printed to form a pattern including ribs delineating flow channels.

A method for cutting an electrode of an electrochemical generator including a metal sheet with a laser beam of a power lower than or equal to 600 W, one face of the metal sheet being partially coated with a thinly layered band called the cutting band, the optical absorption factor of which for an emission wavelength of the laser beam is higher than or equal to 0.5 and preferably higher than or equal to 0.8, and extends so as to define a cutting path, in which the laser beam is focused on the cutting band and the laser beam is animated with a relative movement with respect to the electrode so as to travel the cutting path.
