Title: METHOD FOR PRODUCING A FUEL CELL AND A FUEL CELL
Abstract:
The invention relates to a method for producing a fuel cell, which has at least one membrane-electrode assembly having a first electrode and a second electrode, which are separated from one another by a membrane, and at least one bipolar plate, which comprises a first distribution area for distributing a fuel to the first electrode and a second distribution area for distributing an oxidizing agent to the second electrode, said method comprising the following steps: a) generating a flat fabric (80); b) passing the fabric (80) between two rolls (90), which each have a structured surface (93), as a result of which the fabric (80) is deformed in such a manner that humps (32) are created in the fabric (80); c) arranging the distribution unit (30) created in this way in at least one distribution area of the at least one bipolar plate. The invention further relates to a fuel cell produced by the method according to the invention.
