Abstract: With the help of a method for production of a gaseous diffusion electrode from a silver catalyst on PTFE-substrate, it is endeavored to achieve results which can be reproduced, by avoiding the disadvantages of the state-of-the-art technology, whereby this is achieved in that the porous system of the silver catalyst is filled with a wetted fluid; a dimension-stable solid body with a grain size above that of the silver catalyst is mixed below the silver catalyst; the thus compression-stable mass is shaped into a homogenous catalyst band in a calender; and in a second calender step, an electrically conductive conductor material is imprinted into the catalyst band.
