Embodiment
[0014] Example: A temperature control switch and its application in a fuel cell cathode intake system
[0015] The fuel cell cathode air intake system of this embodiment includes an oxygen gas source, an air pump, a fuel cell cathode air inlet, and a gas pipeline connecting the above three in series; a temperature control switch is provided on the Inside the gas pipeline between the fuel cell cathode inlet and the gas pump.
[0016] The temperature control switch includes a temperature control spring, a one-way valve, and a flexible connection chain connecting the two;
[0017] The one-way valve includes a valve core and a valve seat, and the valve core and the valve seat are connected by an asymmetric shaft; the flexible connecting chain and the one-way valve core are connected in an eccentric hinge form, so that the flexible connecting chain is connected with the valve core. The valve core forms a laborious lever;
[0018] The end of the temperature control spring away from the che...
