Description
Technical Field
The utility model relates to a hydrogen recovery unit for hydrogen fuel cell especially relates to a collect hydrogen fuel cell exhaust tail gas to with hydrogen retrieve and the hydrogen recovery unit who recycles in the tail gas.
Background
After hydrogen of the existing hydrogen fuel cell enters a fuel cell stack and electrochemical reaction occurs, part of unreacted hydrogen and generated water are discharged as tail gas. For example, a hydrogen fuel cell 10P shown in fig. 1 has an inlet 11P, an inlet 12P communicating with the inlet 11P, and an outlet 13P communicating with an internal flow passage of the hydrogen fuel cell 10P, wherein the inlet 12P is also communicated with the internal flow passage of the hydrogen fuel cell 10P, wherein the hydrogen fuel cell 10P is fed with hydrogen gas from the inlet 11P, the hydrogen gas is fed from the inlet 11P, and fed into the internal flow passage of the hydrogen fuel cell 10P through the inlet 12P to participate in an electrochemical reaction, and since the electrochemical reaction generates a certain amount of water, the water inside the hydrogen fuel cell 10P needs to be discharged at certain time intervals, the outlet 13P side of the hydrogen fuel cell 10P communicates with an electromagnetic valve 20P, and the water inside the hydrogen fuel cell 10P is discharged through the outlet 13P and the electromagnetic valve 20P in sequence, it is noted that, when the solenoid valve 20P performs the water discharge, a part of the hydrogen gas is discharged to the outside air. Further, in practical application scenario, the solenoid valve 20P needs to be actuated once every few seconds, the longer the actuation duration, the more hydrogen is discharged to the air, taking an exhaust pipe with a diameter of 6mm as an example, the actuation interval period of the solenoid valve 20P is 10S, the actuation duration of the solenoid valve 20P is 200mS, the hydrogen exhaust pressure is 1Bar, the single hydrogen exhaust volume of the solenoid valve 20P is 300mL, and the exhaust volume of 2.592m after one day is 2.592m3。
In summary, the drawbacks of the tail system of the hydrogen fuel cell 10P include the following: 1. discharging the hydrogen gas at the tail end of the hydrogen fuel cell 10P into the air directly reduces the efficiency of use of the hydrogen gas. At this time, it should be noted that the hydrogen gas at the tail end of the hydrogen fuel cell 10P is directly discharged into the air, which causes waste of the hydrogen gas and reduces the use efficiency of the hydrogen gas. 2. The cost of preparing high-purity hydrogen is higher at present, and certain environmental pollution exists in the preparation process. It should be noted that the high-purity hydrogen production cost is relatively high, the process is complicated, the use efficiency of hydrogen is low, and therefore more high-purity hydrogen has to be produced even under the same requirement, and further, products including carbon monoxide and carbon dioxide are brought in the process of producing high-purity hydrogen, which pollutes the ecological environment. 3. There are economic losses and waste of energy to directly discharge the hydrogen gas at the tail end of the hydrogen fuel cell 10P into the air. The direct discharge of hydrogen to the air as a necessary energy source is equivalent to causing direct economic losses. If not improved, the economic losses due to day-to-day energy waste do not vary significantly.
