Abstract
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 (′) on the surface of the top side () and the point (′) opposite this point (′) 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.
