The proton exchange membrane fuel
cell (PEMFC) has a significant potential for use in a variety of applications,
such as transportation, backup, and portable power, although there are still remaining
technical and cost challenges that must be solved for commercialization. The
DOE has recognized the importance of the gas diffusion layer (GDL) and has
requested innovative GDL designs that will improve the water management
properties, corrosion resistance, and provide improved thermal and electrical
properties. In this program AvCarb
Material Solutions (AMS) takes a multi-faceted approach to cost effectively
alter state of the art GDL designs in a manner consistent with mass production,
specifically focusing on improved water management and thermal/electrical properties. The main objective of this
work is to demonstrate economical processes by which we can produce high
quality GDLs with enhanced properties that will lead to improved performance
under a variety of different operation conditions. The requirements for optimal
GDL performance in hot-dry conditions,
when the membrane risks drying out and losing performance, and cool-wet
conditions, when the GDL can be prone to flooding due to excess water, are very
different. Each work task in this proposal, therefore, focuses on developing a
process to modify one aspect of the GDL that may influence overall performance
for a given condition. It is necessary to develop a firm understanding of how
these processes can alter the GDL structure to improve performance in these
extreme conditions. Improving the
quality and performance of the GDL is instrumental to mass adoption of fuel
cells. Fuel cells provide clean energy generation for a variety of applications,
severely reduce the amount of greenhouse gas (GHG) emissions, and reduce the
reliance on foreign oil to make the U.S. more energy independent. There are
also economic benefits for this program, as AvCarb is the only domestic source
of GDL substrate material. AvCarb currently has the capacity to produce over
100,000 m2 of
GDL per year, which puts them in a strong position as a global supplier. It is
in the best interest of the general public and, more specifically, the DOE to
ensure that we have a viable domestic source of high-quality and high
performance GDL materials for current and next generation fuel cell projects.
