Abstract

The invention relates to a method for producing a flow plate (10, 28) for a fuel cell (12), comprising a plurality of gas guide webs (14) and at least one electrically conductive and porous layer unit (16) arranged on the gas guide webs (14). It is proposed that a geometry and/or a structure of the layer unit (16) is produced during a material application onto the gas guide webs (14).
