Integrated Manufacturing for Advanced MEAs

PDF Version Also Available for Download.

Description

This program addressed a two-pronged goal for developing fuel cell components: lowering of precious metal content in membrane electrode assemblies (MEAs), thereby reducing the fuel cell cost, and creating MEAs that can operate at 120oC and 25% RH whereby the system efficiency and effectiveness is greatly improved. In completing this program, we have demonstrated a significant reduction in precious metal while at the same time increasing the power output (achieved 2005 goal of 0.6g/Kw). We have also identified a technology that allows for one step fabrication of MEAs and appears to be a feasible path toward achieving DOE’s 2010 targets ... continued below

In completing this program, we have demonstrated a significant reduction in precious metal while at the same time increasing the power output (achieved 2005 goal of 0.6g/Kw). We have also identified a technology that allows for one step fabrication of MEAs and appears to be a feasible path toward achieving DOE’s 2010 targets for precious metal and power (approaches 0.2g/Kw). Our team partner Du Pont invented a new class of polymer electrolyte membrane that has sufficient stability and conductivity to demonstrate feasibility for operation at 120 oC and low relative humidity. Through the course of this project, the public has benefited greatly from numerous presentations and publications on the technical understanding necessary to achieve these goals.
