The invention discloses a water balance system of a fuel cell. The water balance system of a fuel cell comprises a water / vapor separator and a water pump, wherein the water / vapor separator is arranged on an exhaust gas channel of a fuel cell stack; the water pump is connected to the bottom of the water / vapor separator so as to pump the liquid water generated at the bottom of the water / vapor separator to a fuel cell water tank; and a refrigerating plant is arranged at the side of the water / vapor separator. Preferably, the refrigerating plant comprises a controller, a semiconductor refrigerating sheet, a first fin, a second fin and a radiator fan, wherein the first fin is arranged at the refrigerating side of the semiconductor refrigerating sheet; the second fin is arranged at the radiating side of the semiconductor refrigerating sheet; the radiator fan is arranged at the outer side of the second fin; the semiconductor refrigerating sheet is arranged externally at the side of the water / vapor separator; and the controller is connected to the semiconductor refrigerating sheet and the radiator fan. Compared with the prior art, by using the system disclosed by the invention, water and vapor are separately more thoroughly; steam is returned to the water tank of the system fully and recycled to humidify hydrogen and air; and water balance of the fuel cell system is realized greatly.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell water balance system. Background technique [0002] A proton exchange membrane fuel cell is a device that can convert hydrogen into electrical energy and reaction products; the internal core component of the device is the membrane electrode, which is generally placed between two conductive plates, each conductive plate and The surfaces in contact with the membrane electrodes are provided with diversion grooves. These diversion grooves not only serve as channels for fuel and oxidant to enter the anode and cathode surfaces, but also serve as channels for taking away water generated during the operation of the fuel cell. [0003] A fuel cell power generation system usually includes a fuel cell stack, a hydrogen storage device, a pressure reducing valve, an air filter device, an air compression supply device, a water vapor separator, a water tank, a cooling device, a h...
