The invention relates to an exhaust control method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: a control unit obtains the volume of nitrogen in a cathode inlet, the current value of a current converter connected with an electric pile and the hydrogen in-pile pressure of an anode inlet; the control unit determines the density of the gas in the electric pile according to the volume of the nitrogen in the cathode inlet and the hydrogen in-pile pressure; the control unit determines the required gas displacement according to the current value of the current converter connected with the electric pile and the current integral value in the preset time period; the control unit determines exhaust starting time based on the density of the gas in the electric pile and the required gas displacement; the control means controls the opening and closing of the exhaust valve on the basis of the exhaust opening time. By adopting the method, the exhau
