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 method for the recovery of precious metal from materials containing precious metal, said method comprises the following steps of: A) bringing the materials containing the precious metal into contact with an oxidizing agent, B) bringing the material containing the precious metal into contact with a reducing agent. Said method offers the possibility of recovering precious metal in a simple manner and in high purity from secondary materials.

Method for the recovery of precious metal

The present invention refers to highly sinter-stable metal nanoparticles supported on mesoporous graphitic spheres, the so obtained metal-loaded mesoporous graphitic particles, processes for their preparation and the use thereof as catalysts, in particular for high temperature reactions in reducing atmosphere and cathode side oxygen reduction reaction (ORR) in PEM fuel cells.

Highly sinter-stable metal nanoparticles supported on mesoporous graphitic particles and their use

The present invention relates to the use of mesoporous graphitic particles having a loading of sintering-stable metal nanoparticles for fuel cells and further electrochemical applications, for example as constituent of layers in electrodes of fuel cells and batteries.
