The invention relates to the technical field of fuel cell system power distribution, in particular to a power distribution method and device of a fuel cell system and the fuel cell system.The method comprises the steps that S101, the current required power Preq of the fuel cell system is obtained; s102, matching a power distribution strategy of the fuel cell system according to the current required power Preq; and S103, performing power distribution on the first sub-fuel cell system, the second sub-fuel cell system and the battery pack in the fuel cell system according to the power distribution strategy. According to the power distribution method of the fuel cell system provided by the embodiment of the invention, the problems of low power generation efficiency and high energy consumption when the fuel cell system is used for power distribution are solved, and more power is distributed to the high-efficiency interval of the fuel cell, so that the operation efficiency is improved when two same fuel cell systems are operated in parallel, and the energy consumption is reduced. Energy conservation and environmental protection are realized.

    本发明涉及燃料电池系统功率分配技术领域,特别涉及一种燃料电池系统的功率分配方法、装置及燃料电池系统,其中,方法包括:S101.获取燃料电池系统的当前需求功率Preq;S102.根据当前需求功率Preq匹配燃料电池系统的功率分配策略;S103.根据功率分配策略对燃料电池系统中第一子燃料电池系统、第二子燃料电池系统和电池包进行功率分配。根据本发明实施例的燃料电池系统的功率分配方法,解决了在使用燃料电池系统进行功率分配时,发电效率低、耗能大的问题,通过将更多功率分配到燃料电池的高效区间,从而使两个相同燃料电池系统并联运行时提高运行效率,实现节能环保。
