Electrode for electrolytic cells Membrane comprising a metal substrate with at least one surface is provided with grooves, the depth of the grooves is 0.001 0,1 mm, and the distance between adjacent grooves is 0.1 to 0.5 mm; EC

摘要

The invention relates to an electrode for membrane electrolysis cells comprising a grooved metal support favouring the gas release and the electrolyte renewal on its surface. The grooved geometry of the support may be obtained by erosion of a metal sheet with abrasive media in a continuous process.
