New membrane electrode assembly architecture (MEA architecture) for improved durability for a PEM fuel cell

摘要

An electrically conductive fluid distribution element for use in a fuel cell having a layer of conductive non-metallic fibrous microporous media. In certain embodiments, an electrically conductive metal is deposited along a surface of the element to form a metallized region or multiple metallized regions. The metallized regions are arranged to contact a membrane electrode assembly (MEA) in a fuel cell assembly, thus improving electrical conductivity in the contact regions between the MEA and the layer of media. Methods of making such a fluid distribution element and operating the fuel cell assemblies are also provided.
