Controlled Porosity and Surface Coatings for Advanced Gas Diffusion Layers
Physical Sciences Inc. (PSI) has been awarded a contract from the Department of Energy to develop a novel and cost-effective process to produce carbon-based gas diffusion layers (GDLs).
Polymer electrolyte membrane fuel cells (PEMFCs) are a leading candidate as an alternative energy source for light duty vehicles. However, their current performance is inadequate for this application. Gas diffusion layers (GDLs) are a critical component of the PEMFC that contribute significantly to the overall performance. Improving the properties of GDLs will allow for wide-scale adoption of the PEMFC and thus enhanced US energy.
The GDLs produced by PSI in this effort will be applied to light duty transportation applications to provide enhanced durability and performance. Wide adoption of PEMFCs for transportation applications will reduce dependence on petroleum fuels and limit greenhouse gas emissions.
