Abstract

A process is described for the production of electrodes for, for example, fuel cells by applying an ink consisting of a mixture of at least a carbon powder, an ion-conducting polymer and a fluid, the fluid containing at least 3 % of an alkanediol, and a fuel cell electrode which can be obtained by applying such an electrode ink to a substrate, followed by a heat treatment. The fuel cell electrode is very suitable for use in solid polymer fuel cells.
