The invention provides a fuel cell humidifying system, a control method, a fuel cell and a vehicle. The fuel cell humidifying system comprises a spraying cavity, a spraying water pump, a water segregator and a water tank, air and liquid water are separated from water discharged from the air side of a fuel cell stack through the water segregator, and the separated liquid water is stored in the water tank; liquid water in the water tank is pressurized and atomized through the atomizing water pump, and the atomized water is mixed with dry air entering the air inlet of the electric pile in the atomizing cavity; a radiator and a heater are arranged on the water tank and used for adjusting the temperature of liquid water in the water tank. A radiator and a heater are arranged on the water tank, the temperature of in-pile air is further adjusted by adjusting the temperature of liquid water, and a membrane humidifier and an intercooler are omitted. The elimination of the intercooler reduces the air side flow resistan
