Stationary fuel cell power systems - Part 4.
Performance test methods for small fuel cell power
systems
1 Scope
This Part of GB/T 27748 provides test methods for the electric/thermal and
environmental performance of small stationary fuel cell power systems that
meet the following criteria.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.
IEC 61672-1, Electroacoustics - Sound level meters - Part 1.Specifications
IEC 62282-3-200, Fuel cell technologies - Part 3-200.Stationary fuel cell
power systems - Performance test methods
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
condition of a fuel cell power system at ambient temperature with no power
input or output, ready for start-up
4 Symbols
The symbols and their meanings used in this Part are given in Table 1 for
electric/thermal performance and Table 2 for environmental performance, with
the appropriate units.
5 Configuration of small stationary fuel cell power system and test boundary
Figure 2 illustrates the general configuration of small stationary fuel cell power
systems subject to this standard and shows the test boundary and physical
quantities entering and leaving the fuel cell system.
6 Reference conditions
The reference conditions are specified as follows.
7 Heating value base
The heating value of fuel is based on the lower heating value (LHV) in principle.
In cases where LHV is applied for the calculation of energy efficiency, it is not
necessary to add the symbol "LHV", as shown below.
8 Test preparation
An uncertainty analysis shall be performed on the three test items below to
indicate the reliability of the test results and to comply with customer requests.
The following test results shall be analysed to determine the absolute and
relative uncertainty. A test shall be planned so that the reliability of the results
can be evaluated for the following.
9 Test set-up
Figure 3 illustrates an example of the test set-up that is required to conduct
small stationary fuel cell power system testing with gaseous fuel described in
this standard. An electric load and a thermal load are connected to a fuel cell
power system.
