Effect of γ-ray irradiated MWCNTs on electrical conductivity of a PET/graphite composite for a bipolar plate application

Kim D-H., Son Y., Kongju National University, KR

The effects of a compounding method and γ-ray treated multiwall carbon nanotubes (MWCNTs) on the electrical conductivity of graphite/PET composites were investigated. We found that dispersion of MWCNTs in the PET phase plays a critical [...]

Nanostructured and Self-Assembled Superhydrophilic Bipolar Plate Coatings for Fuel Cell Water Management

Dadheech G., Abd Elhamid M., Blunk R., General Motors Corporation, US

A stably superhydrophilic coating is required on composite and metal bipolar plates to manage byproduct liquid water and, in turn, to enable good PEM fuel cell performace under low power vehicle operating conditions. Silica-based coatings, [...]
