including fuel cell stack and fuel cell auxiliary system; it can work as normal
under external hydrogen source
3.4.4 fuel cell auxiliary system
including. air supply system, fuel supply system (or hydrogen supply system),
water / thermal management system, control system, security system, etc.
3.5.1.3 maximum allowable working pressure, MAWP
the maximum gage pressure at which system or part certified by relevant
regulations or instructions can work
3.5.1.4 maximum operating pressure
the maximum working pressure of internal fuel and oxidant at which fuel cell
specified by manufacture can continuously work safely
3.5.1.5 allowable differential working pressure
the maximum pressure difference between each fluid specified by manufacturer,
of which the fuel cell module can withstand and not damage or permanently
lose functions or characteristics
3.5.1.6 maximum power
the maximum power value which the system or component can output
3.5.1.7 maximum operating temperature; MOT
the maximum transient or steady-state temperature of which the system or
component can perform non-failure work
3.5.2 Test methods for performance of fuel cell system
3.5.2.1 standby state
the state of which fuel cell system is well prepared for start and can start any
time under start order

the time required by fuel cell system from standby state to rated power state,
including rated power cold start and rated power hot start
3.5.2.7 start response time to idle state
the time of fuel cell system from standby state to idle state, including idle cold
start and idle hot start; it can operate stably after it reaches to idle state
[Translator. 3.5.2.8 is not existed in Chinese version]
3.5.2.9 heat recovery efficiency (of a fuel cell power system)
the ratio between fuel cell system recovery heat and fed fuel heating value (low
heat value) of fuel cell system
3.5.2.10 fuel cell engine net output power
the power left after fuel cell stack output power minus the power consumed by
auxiliary system
