The invention provides a performance recovery method and device for a fuel cell and a vehicle, and the method comprises the steps: obtaining a target identifier, and obtaining a target vehicle speed under the condition that the target identifier is that an engine is in a running state and the cumulative recovery duration is greater than a first threshold value and/or the battery performance loss is greater than a second threshold value; under the condition that the target vehicle speed is 0, target reserve and target electric quantity are obtained, and under the condition that the target reserve is larger than a third threshold value and the target electric quantity is smaller than a fourth threshold value and larger than a fifth threshold value, a recovery function is activated; and under the condition that the target vehicle speed is not zero, the target electric quantity and the target reserve are obtained, and under the condition that the target electric quantity is larger than a sixth threshold value and
