ABSTRACT:
A process for the production of electrodes for fuel cells includes 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.
