TECHNOLOGY OVERVIEW

Some challenges faced during the fabrication of the proton exchange membrane in fuel cells include high costs incurred from multi-step metal ink production, potential overloading of metal and restricted substrate choices.

The technology comprises of proprietary platinum-based catalyst ink formulations that allows for a simplified process to fabricate proton exchange membrane fuel cells. During membrane production, metal particles can be grown directly on the substrate and cured with low temperature cold plasma (<70°C). This technology can minimize the platinum loading over a wide range of substrates, thereby reducing the cost of producing fuel cell membranes.
