FIELD: electrochemistry; modification of electrodes used in electrochemical process and methods of regeneration of electrodes. SUBSTANCE: electrode has sheet consisting of inclined strips, type "shutters". Secured to this sheet is grid provided with electrocatalytic coat of the same profile; profiles of sheet and grid coincide. Electrode may be made from metal sheet having waste electrocatalytic coat. Best version of regeneration of electrode made from metal sheet with waste electrocatalytic coat which has profile of "shutter" type consists in using grid with electrocatalytic coat made from the same metal as sheet. Grid is profiled by means of suitable equipment for obtaining profile of "shutter" type. Grid is so positioned on sheet that its profile and profile of sheet coincide. Grid is secured on sheet by welding. Thin sheet with electrocatalytic coat may be used instead of grid for regeneration of electrode. EFFECT: avoidance of difficulties pertaining to geometry of contact surface between diaphragm and electrode, type "shutter"; facilitated procedure of regeneration of waste coat. 14 cl, 7 dwg
