The invention discloses a fuel cell power output control method and device. The method comprises the steps that the whole vehicle required power of a vehicle, the SOC value of a power cell, the vehicle speed of the vehicle and the power parameter of the fuel cell are obtained; determining the first output power of the fuel cell based on the vehicle demand power, the SOC value and the power parameter; determining second output power of the fuel cell based on a power parameter and the vehicle speed; and determining the smaller value in the first output power and the second output power as the target power of the actual working output of the fuel cell. Working noise of the fuel cell can be suppressed on the basis of not increasing hardware, and space arrangement of the whole vehicle is facilitated.

    本发明公开了一种燃料电池功率输出控制方法及装置,其中方法包括:获取车辆的整车需求功率、动力电池的SOC值、车辆的车速以及燃料电池的功率参数;基于整车需求功率、SOC值和功率参数,确定燃料电池的第一输出功率;基于功率参数以及所述车速,确定燃料电池的第二输出功率;将第一输出功率和第二输出功率中的较小值,确定为燃料电池实际工作输出的目标功率。本发明可在不增加硬件的基础上抑制燃料电池的工作噪声,有利于整车空间布置。
