The invention relates to a distributor structure (), particularly a bipolar plate for a stack structure () of a fuel cell or of an electrolyser. The distributor structure () comprises a channel structure () that interacts with at least one polymer membrane (). The distributor structure () is designed as a plastic part () that has electrically conductive properties.

Distributor structure for a fuel cell or electrolyser

An electrode material () for a fuel cell (), comprising a planar body () made of an electrically conductive foam having an open and continuous porosity for at least one operating medium of the fuel cell (), wherein the planar body () has a top side () and a bottom side (), and wherein the thickness () of the material across all points (') on the surface of the top side (), measured in each case between a point (&#x2032;) on the surface of the top side () and the point (&#x2032;) opposite this point (&#x2032;) on the surface of the bottom side (), varies by at least 10%. An electrode () for a fuel cell (), comprising a planar body () made of an electrically conductive foam having an open and continuous porosity for at least one operating medium of the fuel cell (), wherein the planar body () has a top side () and a bottom side (), and wherein the top side (), and/or the bottom side (), has regions () in which the porosity of the planar body () is reduced by at least 10%. A fuel cell () comprising the electrode (). A method for production.

Electrode material and electrode for operating-medium distribution in a fuel cell

The invention relates to a gas distributor plate for a fuel cell, comprising a first distribution structure for distributing a fuel to a first electrode and a second distribution structure () for distributing an oxidation agent to a second electrode. According to the invention, there is at least one wire element () in at least one of the distribution structures (). The invention further relates to a fuel cell, which comprises at least one membrane electrode unit having a first electrode and a second electrode, which are separated from each other by a membrane, and at least one gas distribution plate according to the invention.
