USE OF DISPERSING AGENTS FOR PREPARING INKS FOR FUEL CELLS

摘要

The present invention relates to the use of a compound as a dispersing agent in a dispersion including said compound, to at least one catalytic pigment conductor and to at least one solvent, said compound including an aromatic hydrophobic portion and a hydrophilic portion including an anionic end and/or a linear chain including at least 12 -OCH2CH2- chain links. The present invention further relates to the use of said compound as a dispersing agent in an ink formulation including said dispersion and a protonic, conducting polymer. The present invention further relates to a dispersion including said compound, suitable for the preparation of an ink formulation for a fuel cell electrode, in particular for a PEMFC, Proton Exchange Membrane Fuel Cell, electrode.
