Researchers at the National Institute of Standards and
Technology 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, 4.0, 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 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
