Foreword
GB/T 27748 “Stationary fuel cell power system” is divided into the following 4 parts:
- Part 1: Safety;
- Part 2: Performance test methods;
- Part 3: Installation;
- Part 4: Performance test methods for small fuel cell power systems.
This Part is Part 4 of GB/T 27748.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part uses translation method to identically adopts IEC 62282-3-201:2013 “Fuel cell technologies - Part 3-201: Stationary fuel cell power systems - 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:
• output: nominal electric power output of less than 10 kW;
• output mode: grid-connected/independent operation or stand-alone
operation with single-phase AC output or 3-phase AC output not
exceeding 1000 V, or DC output not exceeding 1500 V;
NOTE: The limit to 1000 V comes from the definition for "low voltage" given in IEV 601- 01-26.
• operating pressure: maximum allowable working pressure of less than 0.1 MPa (gauge) for the fuel and oxidant passages;
• fuel: gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.);
• oxidant: air.
This Part covers fuel cell power systems whose primary purpose is the
production of electric power and whose secondary purpose may be the
utilization of by-product heat. Accordingly, fuel cell power systems for which the use of heat is primary and the use of by-product electric power is secondary are outside the scope of this standard.
All systems with integrated batteries are covered by this Part. This includes systems where batteries are recharged internally or recharged from an external source.
This Part does not cover additional auxiliary heat generators that produce thermal energy.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 noise level
sound pressure level produced by the fuel cell power system measured at a specified distance in all operation modes
Note: Expressed as decibels (dB) and measured as described in 15.2.
3.2 background noise level
sound pressure level of ambient noise at the measurement point
Note: This measurement is taken as described in 15.2 with the fuel cell power system in the cold state.
3.3 battery
