1. A method for the fabrication of a plurality of material systems, comprising the steps of:
- a) continuously providing a material system composition comprising at least a first material system component and a second material system component;
b) depositing said material system composition onto a substrate; and
c) analyzing at least one material property of said material system composition, wherein a material property of at least one of said first material system component and said second material system component is varied on a real-time basis such that said material system composition comprises a first material system composition at a first time and a second material system composition at a second time.

Abstract
Methods for formulating material systems of varying chemistry and stoichiometry. The material systems include two or more components and can be analyzed to select the system having the best properties for a particular application. Specific examples of materials systems that can be fabricated and analyzed according to the present invention include layers for membrane electrode assemblies (MEA'"'"'s) that are useful in the construction of fuel cells and similar devices.
