Description / Abstract:
This Code applies to all fuel cell power systems regardless of
the electrical power output, thermal output, fuel cell type, fuel
type, or system application.
Fuel cell power systems contain an assembly of electrochemical
cells, which oxidize a fuel to generate direct current electricity.
Balance-of-plant subsystems may include controls, thermal
management, a fuel processor and a power conditioner. Some fuel
cell power systems may contain additional power generating
equipment such as steam generators, gas turbine generators, or
micro-turbine generators. The net power output and all the fuel
input to the system shall be taken into account in the performance
test calculations.
This Code applies to the performance of overall fuel cell power
systems. The Code addresses combined heat and power systems, that
is, the generation of electricity and usable heat at specif c
thermal conditions. It does not address the performance of specif c
subsystems nor does it apply to energy storage systems, such as
regenerative fuel cells or batteries. It also does not address
emissions, reliability, safety issues, or endurance.
This Code contains methods and procedures for conducting and
reporting fuel cell system testing, 2 including instrumentation to
be used, testing techniques, and methods for calculating and
reporting results.
The Code def nes the test boundary for fuel and oxidant input,
secondary energy input and net electrical and thermal energy
output. At these boundaries, this Code provides procedures for
measuring temperature, pressure, input fuel f ow and composition,
electrical power, and thermal output.
The Code provides procedures for determination of electrical eff
ciency or heat rate and overall thermal effectiveness at rated or
any other steady-state condition. The Code also provides the method
to correct results from the test to reference conditions.
