Thermal-Stable proton exchange membranes from nanoblending partially phosphonated graphene into high-temperature polymer matrix

A High Temperature Proton Exchange Membrane for Fuel Cells Fuel cells continue to be highly promising solutions for many transportation problems.  There is a great need for clean energy sources that can replace fossil fuels.  Fuel cells have provided energy for satellites for years, and are now being considered as sources of clean electricity using hydrogen as a fuel source.  However, fuel cells have yet to be used in large numbers in commercial applications.  One of the difficulties is the low fuel-to-electricity efficiency which makes fuel cells uneconomical.  An increase in the fuel-to-electricity ratio would make fuel cells a viable, clean source of electricity. The Proton Exchange Membrane (PEM) is the crucial part of a fuel cell, and its materials properties are of prime importance in the overall efficiency of the fuel cell.  The most important properties of the PEM are the mechanical strength of the membrane and the maximum temperature at which it can operate.  Currently, the maximum temperature at which conventional PEM’s can operate is below 95 degrees C. A new PEM has been invented utilizing a new form of graphene oxide that provides superior mechanical properties. In particular the new PEM can operate at elevated temperatures, in a range from 120 degrees C to 200 degrees C, greatly increasing the fuel-to electricity ratio and making the fuel cell far more efficient. The new PEM is currently patent-pending and is available for license.  For more information, contact; Mark Swaney479-575-7243mswaney@uark.edu Ref 17-17
