When humidifying the reaction gas, the gas humidifying device provided by the embodiment of the present disclosure firstly enters the reaction gas to be humidified into the venturi tube 2 through the first end of the contraction section 21. Since the inner diameter of the first end of the convergent section 21 is greater than that of the second end, when the reaction gas reaches the connection position between the convergent section 21 and the divergent section 22 of the venturi tube 2, that is, the inner diameter of the venturi tube 2 is the smallest, the pressure of the reaction gas is reduced and the flow rate of the reaction gas is increased by the venturi effect to form a "vacuum zone" at the inner diameter smallest of the venturi tube 2. Thus, the water in the water storage tank 1 is quickly sucked into the spray pipe 3 and is sprayed out through the second end of the spray pipe 3.
