This Standard is applicable to the storage test, startup test, working
performance test of proton exchange membrane fuel cell power system at low
temperature environment (subzero) that use air as oxidant.
This Part is applicable to the complete fuel cell power system.
NOTE. According to the needs, realize the locking function. The system consists of some
or all of the following components.
- fuel processing system. a system for metering, adjusting, processing, and pressure-
regulating of fuel needed for fuel cell power system;
- air processing system. a system for metering, adjusting, processing, and pressure-
applying of air needed for fuel cell power system;
- thermal management system. related parts that provide cooling and heat dissipation to
maintain heat balance inside the fuel cell power system, also recover waste heat and
assist the heating system during start-up;
- water treatment system. treat recycled or added water for use in fuel cell power system;
- power regulation system. control that the generated power matches user-specified power
requirements;
- automatic control system. consist of sensors, actuators, valves, switches, and logic
components to maintain fuel cell power system parameters within the manufacturer's set-
up without manual intervention;
