Researchers at the University of Southern Mississippi studied structure-property relationships in order to develop fuel cell membranes capable of operating at high temperatures. As fuel cells must be able to withstand stresses and temperatures up to 120°C at low relative humidity, this research provided a greater understanding of how humidity and temperature variations within the fuel cell degrade the membrane. The research's overall focus has been to evaluate different aromatic hydrocarbon polymers and how they can improve the durability of these types of fuel cells, thereby increasing the lifetime of the fuel cell and reducing its overall cost. The University contributed $483,000 to this project.

The Fuel Cell Technologies Office (FCTO) conducts comprehensive efforts to overcome the technological, economic, and institutional barriers to the widespread commercialization of hydrogen and fuel cells.

The Office of Energy Efficiency and Renewable Energy (EERE) success stories highlight the positive impact of its work with businesses, industry partners, universities, research labs, and other entities.
