A fuel cell control method, control system and electric vehicle. The control method comprises the following steps of determining that the fuel cell is shut down and controlling the fuel cell to enter a standby mode, wherein the standby mode comprises the step of controlling the electric quantity output by the stack module of the fuel cell such that it is used only for maintaining the working temperature of the fuel cell. From the above content, it can be known that according to the technical solution provided by the invention, the low-power consumption standby operation of the fuel cell can be maintained, the temperature of the fuel cell is ensured to be at the working temperature, the heat loss caused by the shutdown of the fuel cell is reduced, the power requirement of a whole vehicle is met in an instant response manner when the fuel cell is started for the second time, the starting time is short, the gas loss and the starting time caused by heating the fuel cell during the second starting are reduced, and the fuel cell does not need to be heated during the second starting, so that the rotating speed of a fan does not need to be increased, and the comfort of the electric vehicle is ensured.
