Researchers at the National Institute of Standards and
Technology (NIST) have measured the performance of a
residential fuel cell system when subjected to various
environmental and load conditions. The system, which
uses natural gas as its source fuel, is capable of
generating electrical power at three nominal power
levels (2.5 kW, 4.0 kW, and 5.0 kW) while providing
thermal energy for user-supplied
loads. Testing was conducted to determine the influence
of ambient temperature, relative humidity, electrical
load, and thermal load on system performance.
Steady-state and transient tests were conducted. The
steady-state tests were performed in accordance with the
American Society of Mechanical Engineering (ASME) Fuel
Cell Power Systems Performance Test Code (PTC-50) for
fuel cell power systems. The results of the
investigation are being used to develop a proposed
rating procedure for residential fuel cell units.
