Title:
METHOD AND APPARATUS FOR ELECTROSTATICALLY COATING AN ION-EXCHANGE MEMBRANE OR FLUID DIFFUSION LAYER WITH A CATALYST LAYER
Document Type and Number:
WIPO Patent Application WO2006031477
Kind Code:
A3
Abstract:
A method and apparatus for coating an ion-exchange membrane or fluid diffusion layer with a catalyst layer for use in an electrochemical fuel cell is disclosed, the method comprising the steps of electrostatically charging a catalyst slurry to yield an electrostatically-charged catalyst slurry, and applying the electrostatically-charged catalyst slurry onto a first surface of the ion-exchange membrane or fluid diffusion layer to form a first catalyst layer on the first surface.
