The invention provides a fuel cell current load rejection control method and a vehicle. The control method for the current load rejection of the fuel cell comprises the following steps: after the fuel cell is started and enters an operation state, when the current load rejection of the fuel cell is detected, adjusting the hydrogen-air pressure difference in an electric pile by controlling a valve of the fuel cell, thereby completing the current load rejection. By adjusting the hydrogen-air pressure difference in the fuel cell stack, the damage of the hydrogen-air pressure difference caused by load rejection to the fuel cell stack is reduced, so that the purpose of prolonging the service life of the fuel cell stack is achieved.

    本发明提供了一种燃料电池电流抛载的控制方法及车辆。其中,燃料电池电流抛载的控制方法,包括:当燃料电池开机进入运行状态后,检测到燃料电池电流抛载时,通过控制燃料电池的阀门,调整电堆内部氢空压差,从而完成电流抛载。通过调整电堆内部氢空压差,降低抛载造成的氢空压差对燃料电堆带来的损害,从而达到提高燃料电池电堆寿命的目的。
