The Department of Energy's Golden Field Office
invites applicants to develop high temperature, low relative humidity
polymer electrolyte-type membrane materials suitable for use in a polymer
electrolyte-type membrane fuel cell. Development of alternative materials
with performance at 120 degrees C and 25-50 percent relative humidity
exceeding that of Nafion(R) (at 80 degrees C and 100 percent relative
humidity) is desired.

Current polymer electrolyte membranes (PEMs) used in fuel cells depend on
the presence of water to obtain high proton conductivity. Therefore, fuel
cells based on these membranes are limited to operating temperatures of
60-80 degrees C and require external humidification to maintain optimum
performance. Maintaining these temperatures under automotive conditions,
especially at peak power, requires over-sized cooling equipment. In
addition, the humidification requirements add increased volume, weight, and
complexity to the system. These issues would be reduced or eliminated if
the fuel cell could be operated at higher temperatures (approximately 120
degrees C) and at lower humidity. Additional benefits of operation at
elevated temperatures and reduced humidity are a reduction in the
occurrence of cathode flooding at peak power, and a possible improvement in
cell performance due to increased rate of the oxygen reduction reaction.
If the pressure of the system is increased, adequate humidification can be
achieved during high temperature operation, however, this leads to
significantly reduced lifetimes and system efficiencies.

High temperature, low humidity membranes are expected to improve thermal
management and ease or eliminate the need for membrane water management in
automotive systems. Higher temperature operation will also aid in
achieving success in combined heat and power applications for stationary
fuel cells.

Membranes that conduct protons at low relative humidity (RH) (i.e., 25-50
percent RH) and temperatures ranging from room temperature to 120 degrees C
have been identified as critical components in achieving system targets for
automotive fuel cell applications. Based on the early stage of development
of such membranes, this Announcement seeks innovative research leading to
new candidate materials.
