GB/T 18384.3-2001 Electric Vehicles - Safety Specification - Part 3.Protection of Persons against Electric Hazards (ISO/DIS 6469-3. 2000, EQV) GB/T 20042.1 Proton Exchange Membrane Fuel Cell - Terminology3 Terms and DefinitionsFor the purposes of this standard, the terms and definitions specified in GB/T 20042.1 and those listed below apply. 3.1 Net output power of power system The remaining power of output power of fuel cell stack deducting the power consumed by the auxiliary system, namely the net output power of fuel cell power system, hereinafter referred to as power of power system. 3.2 Efficiency of fuel cell stack The portion of fuel energy consumed by fuel cell stack in unit time which is transformed to output power; it is specified to calculate it with the low calorific value of hydrogen ( 2HLHV ). Fuel cell power system shall meet the following requirements. - Each system of fuel cell power system shall be complete and capable of normally operating under external source of hydrogen; - Fuel cell power system shall have reliable security assurance system; - Supplement of coolant and humidification water is unallowable during the test of fuel cell power system. 5.2.2 Test conditions The test party shall provide the following test conditions. - High-pressure hydrogen source, with purity meeting the service requirements; - Control power supply (e.g. DC 12V power supply, DC 24V power supply, etc.); - DC auxiliary power supply. 5.2.3 State requirements for fuel cell power system prior to test The state of fuel cell power system prior to test shall meet the following requirements. - Complete the filling of coolant; - The fuel cell power system starts working after connecting the hydrogen. 5.2.4 The manufacturer provides relevant technical parameters of fuel cell power system to the test party.6 Performance Test Methods6.1 Cold method Thermal insulation is carried out for the fuel cell power system (with filling of coolant completed) at specified temperature and humidity for enough time to ensure that the internal temperature of fuel cell power system is the same with ambient temperature, and the standing time is 12h at least. 6.2 Hot method The fuel cell power system is working under specific power according to the application requirements of the manufacturer; meanwhile, the outlet temperature of fuel cell stack coolant is monitored; once the outlet temperature of fuel cell stack coolant reaches the normal working temperature, it is regarded as that the fuel cell power system has reached hot state. 6.3 Routine performance test 6.3.1 Mass of power system The mass (shall also include the mass of coolant and humidification water) of fuel cell stack and auxiliary system (including hydrogen supply system, air supply system, control system, hydrothermal management system and etc.) is measured. 6.3.2 Volume of fuel cell stack The maximum dimensions of fuel cell stack in three directions are measured and the maximum peripheral volume of fuel cell stack is calculated. 6.3.3 Insulation resistance test At the end of the whole test and under no-load cold state condition where coolant and humidification water are filled, the insulation resistance of the anode and cathode output terminals of fuel cell stack relative to the power system case is respectively measured with tramegger, and the insulation resistance conforms to the requirements of GB/T 18384.3-2001. 6.4 Starting characteristic test 6.4.1 Idle starting test 6.4.1.1 Test method a) Pretreatment for cold (see 6.1) or hot (see 6.2) process of fuel cell power system is carried out according to test requirements; b) At the end of pretreatment process, the fuel cell power system is started according to the starting operation procedure suggested by the manufacturer; c) If the fuel cell power system, after being started, can maintain stable operation for 10min under idling state, the idle starting of fuel cell power system is regarded as successful, otherwise failed; d) Test process shall be automatically operated and free of manual intervention. 6.4.1.2 Data processing Data measured during test. starting time, initial temperature of coolant, voltage and current of fuel cell stack; voltage and current of auxiliary system; consumption of hydrogen. 6.4.1.3 Assessment index Starting time. 6.4.2 Starting test at rated power 6.4.2.1 Test method a) Pretreatment for cold (see 6.1) or hot (see 6.2) process of fuel cell power system is carried out according to test requirements; b) At the end of pretreatment process, the fuel cell power system is started according to the starting operation procedure suggested by the manufacturer; c) The test platform controller sends work order to fuel cell power system with the method suggested by the manufacturer and the test platform carries out loading with specified loading method simultaneously; where loaded to the rated power point, the fuel cell power system can maintain stable operation for 10min at rated power, the rated power starting of fuel cell power system is regarded as successful, otherwise failed; d) Test process shall be automatically operated and free of manual intervention. Note. the specified loading (unloading) method is jointly determined through negotiation by the test party, the manufacturer and the user according to service requirements. 6.4.2.2 Data processing Data measured during test. starting time, initial temperature of coolant, voltage and current of fuel cell stack; voltage and current of auxiliary system; consumption of hydrogen. 6.4.2.3 Assessment index Starting time. 6.5 Steady-state characteristic test 6.5.1 Test method a) 10 or more operating points are uniformly selected within the working range of fuel cell power system (power working mode and current working mode may be adopted for the working mode); b) Fuel cell power system is heated according to the method specified in 6.2... ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
