The invention provides a demand power control method and device for a fuel cell; the method comprises the steps: obtaining the power data of a fuel vehicle, and determining the first demand power of the fuel cell based on the power data; determining second required power corresponding to the first required power in a preset power threshold table; and controlling the required power of the fuel cell within the preset time to be the second required power. In the method, first required power is determined based on power data, second required power is determined in a power threshold table, and finally, the required power of a fuel cell within a preset duration is controlled to be the second required power. Therefore, the required power of the fuel cell does not need to be changed in real time according to actual requirements, so that the working stability of the power of the fuel cell is ensured, and therefore, damage to the battery is reduced, and the service life of the system is prolonged.

    本发明提供一种燃料电池的需求功率控制方法及装置,该方法包括:获取燃料汽车的功率数据,基于所述功率数据确定燃料电池的第一需求功率;在预设的功率阈值表中确定与所述第一需求功率对应的第二需求功率;控制所述燃料电池在预设时长内的需求功率均为所述第二需求功率。基于功率数据确定第一需求功率,并在功率阈值表中确定第二需求功率,最后控制燃料电池在预设时长内的需求功率均为第二需求功率,燃料电池的需求功率无需根据实际需求实时的进行变化,由此保证了燃料电池功率工作的稳定,进而减少电池的损伤,提高系统的使用寿命。
