Solid polymer fuel cell (SPFC) systems are expected to see service in
a wide variety of applications, including road vehicles, trains, ships
, undersea power, and small scale stationary power generation. Each ap
plication brings unique requirements in terms of fuel, power, efficien
cy, volume and weight and, consequently, SPFC systems are expected to
take a variety of forms. This paper reviews the development issues whi
ch must be resolved before SPFC systems can enter commercial service.
It includes the results of system studies completed by Rolls-Royce and
Associates during the last two years. Development priorities are high
lighted, particularly for the stack and fuel processing system. Result
s of the testing of a novel compact fuel processing system are present
ed.
