Improved gas diffusion electrodes and method for their production |
摘要 |
Oxygen-consuming electrode comprises at least one carrier in form of a sheet, and a coating with a gas diffusion layer and a catalytically active component. A one side of the oxygen-consuming electrode, faces the liquid or an ion exchange membrane during operation. The electrode further comprises a finely divided hydrophilic component with an average particle diameter of 20-100 nm, preferably 50-70 nm. An independent claim is also included for preparing the oxygen-consuming electrode, comprising applying or spraying the finely divided, hydrophilic component in a form of suspension (0.1-50 wt.%, preferably 1-20 wt.%) on a planar raw electrode, and removing the suspending agent by evaporation. |
