Membrane electrode assembly manufacturing process

Abstract

The present invention relates to a method of making a fuel cell component, the method comprising: providing a substrate with a first side and a second side; forming an electrode on the first side of the substrate, wherein the forming includes depositing a coating composition on the first side of the substrate; applying a support layer onto the electrode formed on the first side of the substrate; inverting the substrate to make the second side of the substrate available for forming an electrode thereon; forming an electrode on the second side of the substrate wherein the forming includes depositing a coating composition on the second side of the substrate. Preferably, the substrate comprises a releasable backing layer on the second side of the substrate, and the method includes the step of (vi) removing the backing layer so as to expose the second side of the substrate to make the second side of the substrate available for forming an electrode thereon.
