The invention discloses a vehicle fuel cell system control method and device and a storage medium. Comprising the steps of determining whether the operation duration of the fuel cell reaches a first preset limit value; determining whether the deviation between the first voltage of the fuel cell running to the evaluation reference current point and the factory voltage is greater than a second preset limit value; when the operation duration or the voltage deviation of the fuel cell is greater than a corresponding preset limit value, controlling the fuel cell to operate at a plurality of cell load points matched with the SOC value of the power cell; acquiring a plurality of second voltages of the fuel cell running at the plurality of cell load points; and obtaining a voltage-current performance curve according to the battery load point and the corresponding second voltage. According to the embodiment of the invention, the operation duration and the voltage deviation of the fuel cell are detected, when any one of the operation duration and the voltage deviation exceeds the preset limit value, the voltage points of the fuel cell operating at the plurality of cell load points are obtained, the voltage-current performance curve is obtained, and the output power correction of the fuel cell stack is completed on line.

    本发明公开了一种车用燃料电池系统控制方法、装置及存储介质。包括:确定燃料电池的运行时长是否达到第一预设限值;确定燃料电池运行至评价参考电流点的第一电压与出厂电压之间的偏差是否大于第二预设限值;在燃料电池的运行时长或电压偏差大于对应预设限值时,控制燃料电池在与动力电池的SOC值匹配的多个电池负载点运行;获取燃料电池在多个电池负载点运行下的多个第二电压;根据电池负载点以及对应的第二电压获得电压‑电流性能曲线。本发明实施例通过检测燃料电池的运行时长和电压偏差,当任一项超过预设限值时,获取燃料电池在多个电池负载点运行下的电压点,获得电压‑电流性能曲线,实现在线完成燃料电池电堆的输出功率校正。
