Do well to meet bearing power change；When bearing power changes stabilization, fuel cell pack is recalculated by controller
Ideal output power, recalculates the optimal hydrogen manufacturing parameter and optimal hydrogen production rate of sodium borohydride hydrogen manufacturing module to realize fuel electricity
Cell system is powered, the stabilization of hydrogen manufacturing.
10. a kind of control method of fuel cell system based on chemical hydrogen manufacturing according to claim 9, its feature exists
In：Bearing power change judgement is specifically included, and the load work(to be analyzed is set by bearing power extraction time setting unit
The time span of rate；
The bearing power of certain time length is represented in the form of discrete point by bearing power discrete unit；
The performance number of the most discrete point of occurrence number is calculated by bearing power decision threshold computing unit, performance number is added
Performance number is subtracted a safety value and is used as minimum decision threshold by one safety value as maximum decision threshold；
Maximum decision threshold and the discrete point less than minimum decision threshold are more than by bearing power final identifying unit statistics
Total number, when total number is more than setting number threshold value, is determined as there is fluctuation by bearing power change；No person, by bearing power
Change is determined as stabilization.
