The invention provides a cold starting method and device of a fuel cell vehicle and the fuel cell vehicle. The method comprises the steps that under the condition that a starting signal for starting a fuel cell is received and a power cell is allowed to be charged, whether the current current of the fuel cell reaches the minimum required current or not is determined based on the allowable charging current of the power cell and the load current of the fuel cell vehicle; under the condition that the current current of the fuel cell does not reach the minimum demand current, determining a difference value between the minimum demand current and the current current of the fuel cell to obtain a target demand current; and the resistor is controlled to work according to the target demand current, so that the current current of the fuel cell can reach the minimum demand current, the fuel cell is subjected to cold start, and the problem that in the prior art, the low-temperature cold start speed of a fuel cell vehicle is low is solved.
