Abstract

A control valve, a humidifier, and a fuel cell system. The control valve (1000) comprises: a valve seat (100) being internally provided with a core cavity (110), and a first flow channel (120), a second flow channel (130) and a third flow channel (140) which are separately communicated with the core cavity (110), the valve seat (100) being provided with a first valve seat opening (121) communicated with the first flow channel (120), a second valve seat opening (131) communicated with the second flow channel (130), and a third valve seat opening (141) communicated with the third flow channel (140), and the first valve seat opening (121) and the second valve seat opening (131) being located at the same side of the valve seat (100). A valve core (200) is rotatably provided in the core cavity (110), and the valve core (200) is provided with a first valve opening (211) and a second valve opening (223) which are communicated with each other. The valve core (200) rotates relative to the valve seat (100) so as to enable the first valve opening (211) to correspondingly communicate with the first flow channel (120) or the second flow channel (130), the second valve opening (223) being used for communicating with the third flow channel (140). Two flow channels that can be controlled to be opened or closed are formed in the valve seat (100), and the first valve seat opening (121) and the second valve seat opening (131) have different communication positions with the humidifier (2000), thus lengths of paths that a cathode reaction gas flows through are different, and different transfer efficiencies of the cathode reaction gas with a humid and hot tail gas are achieved, thereby regulating the humidity of the cathode reaction gas.
