Problems solved by technology

This causes permanent deformation of the various components that make up the MEA
Insufficient compression can also occur due to the manufacturing method and can lead to buckling of the membrane
Buckling of the membrane can lead to cracking in one of the anode and cathode formed on it

Embodiment 1

[0092] Will contain a loading of 0.4mg Pt / cm 2 A cathode catalyst solution of Pt / Vulcan catalyst was applied to the first free-standing outer reinforcement layer (Carbel from W. L. Gore & Associate (Gore), Maryland ? MP30Z) to form the cathode catalyst layer. The DE2020 solution was coated onto the catalyst layer to form a 6 μm thick Nafion ? film layer. The first free-standing outer reinforcement layer, the cathode and the membrane together form a reinforced cathode composite structure.

[0093] will contain a loading of 0.05mg Pt / cm 2 An anode catalyst solution of Pt / Vulcan catalyst was coated onto a second free-standing outer reinforcement layer (Carbel from W. L. Gore & Associate (Gore), Maryland ? MP30Z) to form the anode catalyst layer. The DE2020 solution was coated onto the catalyst layer to form a 6 μm thick Nafion ? film layer. The second free-standing outer reinforcement layer, the anode and the membrane together form a reinforced anode composite structure....

Abstract

Methods of making reinforced membrane electrode assemblies are described. Catalyst coated free standing microporous layers and reinforced membrane electrode assemblies are also described.

Description

[0001] priority [0002] This application is a continuation-in-part of US Patent Application Serial No. 13 / 071,603, entitled "Directed Catalyst Coating on Freestanding Microporous Layer," filed March 25, 2011, which is incorporated herein by reference. technical field [0003] Embodiments described herein generally relate to methods of coating fuel cell components, and more specifically, they relate to coating multiple fuel cell components onto a free-standing external reinforcement structure. Background technique [0004] Fuel cells, sometimes referred to as electrochemical conversion cells, generate electrical energy by processing reactants, for example, by oxidation and reduction of hydrogen and oxygen. Hydrogen can be a very attractive fuel because it is pure and it can be used to efficiently generate electricity in fuel cells. The automotive industry has expended significant resources in the development of hydrogen fuel cells as a source of power for vehicles. Vehicle...
