| 20080305250 | Fabrication Methods for Catalyst Coated Membranes - Fabrication methods for catalyst coated membranes are provided. The methods include exposing a micro-porous membrane to a catalyst dispersing solution to form a catalyst containing micro-porous membrane. The methods also include exposing the catalyst containing micro-porous membrane to a resin dispersing solution to form a catalyst layer and placing a proton exchange membrane between two of the catalyst layers with a laminating process to form the catalyst coated membrane. The fabrication methods provide filling process to uniformly fill the catalysts and resin throughout the pores of the micro-porous membranes in the catalyst layers. These micro-porous membranes are hydrophobic and easily discharge water when necessary. Therefore, membrane electrode assemblies with catalyst coated membranes fabricated using the provided methods are stable and perform well during fuel cell operation. | 12-11-2008 |
