A fuel cell water washing and degassing system

Abstract

This invention relates to the field of fuel cell technology and discloses a fuel cell water washing and degassing system. The hydrogen output port of the reforming hydrogen production module is connected to the first inlet of a water washing and cooling device. The first outlet of the water washing and cooling device is connected to the anode inlet of the fuel cell stack. The second outlet of the internal cooling pipe of the fuel cell stack is connected to the third inlet of a first water tank via a first water pump. The third outlet of the first water tank is connected to the second inlet of the internal cooling pipe. The first overflow port of the first water tank is connected to the first input port of a dehydration device. The drain port of the dehydration device is connected to the first inlet of the water washing and cooling device via a second water pump. The first outlet of the water washing and cooling device is connected to the fourth inlet of a second water tank. The fourth outlet of the second water tank is connected to the second input port of the dehydration device via a third water pump. This invention washes the hydrogen produced from reforming hydrogen production without requiring an external water source and can treat the exhaust water from the water washing and cooling device.
