The invention discloses a vehicle fuel cell start-stop control method and device, electronic equipment and a medium, and the method comprises the steps: obtaining a power battery SOC value, a vehicle running speed, a whole vehicle power demand value and a hydrogen system pressure value based on the condition that a fuel cell vehicle is in a hybrid running mode and the whole vehicle working condition is in a normal state; according to the incidence relation between the SOC value of the power battery and a preset SOC threshold value and between the SOC value of the power battery and the running speed of the vehicle and the size relation between the power demand value of the whole vehicle and the preset discharge power of the power battery, the starting condition of the fuel battery is determined; and on the basis of the started fuel cell, according to the running state of the vehicle, the size relation between the pressure value of the hydrogen system and the pressure threshold value and the size relation between the SOC value of the power cell and the preset SOC threshold value, the fuel cell closing condition is determined. According to the invention, the purpose of determining the optimal start-stop time of the fuel cell according to the actual demand and the driving state in allusion to different driving conditions and vehicle characteristics is achieved.
