Method and device for determining a distributor field for distributing a medium in a bipolar plate of a fuel cell

Abstract

The invention relates to a method and a device for determining a first distributor field (102) for distributing a first medium in a first bipolar plate (100) of a fuel cell (300), wherein: at least part of the first distributor field (102) is part of an electrochemically active region (106); the electrochemically active region (106) has an active surface; the active surface (108) is divided into surface elements (110); an in particular two-dimensional first geometry of the first distributor field (102) is determined depending on the results of simulations in each of the surface elements (110) of an electrochemical reaction of the first medium with a second medium and a flow of the first medium and a flow of the second medium and a flow of a third medium produced in the electrochemical reaction and a flow of a fourth medium that cools the electrochemical reaction; an in particular three-dimensional second geometry of the first distributor field (102) is determined depending on a result of a simulation in the active region (106) of an electrochemical reaction of the first medium with the second medium and the flow of the first medium and the flow of the second medium and the flow of the third medium and the flow of the fourth medium, on the basis of the first geometry of the first distributor field (102); and the first distributor field (102) is determined in the first bipolar plate (100) on the basis of the second geometry.
