Abstract

Disclosed are a reversing valve and a fuel cell system. The reversing valve comprises: a valve seat (100), the valve seat (100) being internally provided with a first flow channel (110) and a second flow channel (120) in communication with and perpendicular to the first flow channel, the valve seat (100) being provided with a first inlet (111) and a first outlet (112) both in communication with the first flow channel (110), and the valve seat (100) being provided with a second inlet (121) in communication with the second flow channel (120); and a valve core (200), the valve core (200) being internally provided with a third flow channel (210) coaxial with the second flow channel (120), and the valve core (200) being provided with a valve core inlet (211) and a valve core outlet (212) both in communication with the third flow channel (210). An arrangement position of the valve core inlet (211) corresponds to the arrangement position of the second inlet (121), and the valve core (200) is movably arranged in the second flow channel (120), such that the valve core outlet (212) is switched between a position corresponding to the first outlet (112) and a position staggered with the first outlet (112). The reversing valve automatically switches the position of the valve core outlet in the valve seat according to a pressure size, thus automatically achieving flow channel switching. The reversing valve does not have a relatively narrow flow channel during use, and has a small flow resistance and a small pressure loss.
