METHOD AND DEVICE FOR MANUFACTURING OF SEPARATOR FOR POLYMER-ELECTROLYTE FUEL ELEMENT Russian patent published in 2014 - IPC H01M8/02 B21D13/04 H01M8/10 H01M2/14 

FIELD: electricity.

SUBSTANCE: suggested invention relates to the field of electric engineering and namely to the method for manufacturing out of sheet material of a separator for a fuel element containing shaped or profiled crowns and concavities and the device for manufacturing of the above separator. The suggested method envisages elimination of the play between rolls (13) and main bearings (12) at the non-formed section and formation of material to be formed at the formed section, repeated at simultaneous permanent elimination of the play between a body (10) for the rolls (13) and axle boxes (11) of the main bearings thus ensuring manufacture of the separator out of a very thin sheet material with improvement of its dimensions accuracy and this is the technical result of the invention.

EFFECT: suggested device for manufacture of the separator can eliminate the play between rolls in the vertical and horizontal directions with control of loads during formation.
