Abstract

The present invention is related to the field of membrane electrode assembly manufacture. It provides a method for true zero-gap membrane electrode assembly, comprising casting an electrode slurry onto an electrode separator slurry or an electrode separator to form a combination (100), followed by a phase inversion step that induces the formation of the membrane electrode assembly in situ (102). The electrode separator can be a polymeric, polymer-inorganic composite, cation exchange, anion exchange, bipolar or amphoteric membrane. The electrode slurry may include an anode or cathode slurry, and can contain a catalyst, binder, or conductive material. The phase inversion step involves exposing the combination to a non-solvent, such as water or alcohols, at temperatures ranging from about -10 °C to about 100 °C.
