Electrodes for electrochemical fuel cell have catalytic layer in direct contact with gas diffusion layer containing carbon powder and water-repellent high polymer, e.g. polytetrafluoroethylene

摘要

In an electrochemical fuel cell, which has an electrolyte membrane in contact with an electrode on both sides and a separator on the other side of each electrode, the electrodes have a catalytic layer in direct contact with a gas diffusion layer containing carbon powder and a water-repellent high polymer. An Independent claim is also included for the production of the electrodes.
