The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The present invention provides a fuel cell engine air supply system, fig. 1 is a schematic structural diagram of a first embodiment of the fuel cell engine air supply system of the present invention, and as shown in fig. 1, the fuel cell engine air supply system includes a fuel cell stack 101, a main air supply path 110, a main exhaust path 210, a bypass air supply path 120, and a driving motor 102.
One end of the main gas supply path 110 is connected to the cathode inlet of the fuel cell stack 101, and the other end of the main gas supply path 110 communicates with the external environment, so that the main gas supply path 110 can supply gas to the cathode of the fuel cell stack 101. The main air supply path 110 is provided with a compressor 111, and the compressor 111 presses air of the external environment into the main air supply path 110 to make the air flow into the cathode of the fuel cell stack 101.
One end of the main exhaust path 210 is connected to the cathode outlet of the fuel cell stack 101, and the other end is communicated with the external environment, so that the main exhaust path 210 exhausts the gas to the external environment. A turbine 211 is provided in the main exhaust path 210, and the turbine 211 can use the air in the main exhaust path 210 to perform work.
One end of an output shaft of the driving motor 102 is connected with the compressor 111, the other end of the output shaft of the driving motor 102 is connected with the turbine 211, the driving motor 102 can drive the compressor 111 to rotate, and the other end of the driving motor 102 is also connected with the turbine 211, so that exhaust energy recovered by the turbine 211 can be directly transmitted to the compressor 111 through the output shaft of the driving motor 102, and power consumption of the driving motor 102 is reduced. In one embodiment, the output shaft of the drive motor 102 is supported by an air bearing, the air supply line of which is integrated in the compressor 111 and the air exhaust line of which is integrated in the turbine 211.
As shown in fig. 1, one end of the bypass branch line 120 is connected to the main supply line 110, and the connection point is located after the compressor 111, and the other end of the bypass branch line 120 is connected to the main exhaust line 210, and the connection point is located before the turbine 211, where "front" and "rear" refer to a place where air flows first and a place where air flows later are "front" and "rear" respectively, in terms of the flow direction of air. The bypass air supply branch 120 is provided with an air bypass valve 121, which is an electromagnetic valve capable of controlling the flow and the stop of the air in the bypass branch and adjusting the flow rate. Due to the arrangement of the air supply bypass branch 120, the air flow of the air supply bypass branch 120 can be adjusted by controlling the opening of the air bypass valve 121 on the air supply bypass branch 120, when the fuel cell stack 101 enters a low-load working condition, the air bypass valve 121 is opened, and part of air of the main air supply path 110 is bypassed from the air supply bypass branch 120, so that the flow of the air compressor 111 is ensured to be larger than a surge limit, and meanwhile, the air flow required by the fuel cell stack 101 can be ensured. Since the outlet of the bypass air supply branch 120 is located in front of the inlet of the turbine 211, the air of the bypass air supply branch 120 can do work on the turbine 211, and the turbine 211 can recover part of energy additionally consumed by the compressor 111 due to surge prevention, thereby reducing energy consumption of the driving motor 102.
Referring to fig. 1, in one embodiment, a back pressure valve 212 is disposed on the main exhaust path 210, and the back pressure valve 212 can control the cathode pressure of the fuel cell stack 101. The turbine 211 has a capability of building an air supply system pressure, which refers to the cathode pressure of the fuel cell stack 101, during normal operation, so that the back pressure valve 212 is fully opened as much as possible, so that more air flows through the turbine 211, which is beneficial for the turbine 211 to recover more energy, and when the pressure built by the turbine 211 is insufficient, that is, the cathode pressure of the fuel cell stack 101 is insufficient, the back pressure valve 212 is adjusted to reduce the opening of the back pressure valve 212, so as to assist the turbine 211 in building the air supply system pressure, which makes the cathode of the fuel cell stack 101 have sufficient pressure.

The turbine bypass valve 221 is normally closed, and when the back pressure valve 212 is fully opened and the cathode pressure of the fuel cell stack 101 is still greater than the target pressure, the turbine bypass valve 221 is adjusted to increase the opening of the turbine bypass valve 221, and part of the gas flows out through the turbine bypass branch 220 to reduce the cathode pressure of the fuel cell stack 101.

The gas-liquid separator 213 separates liquid water in the cathode exhaust gas of the fuel cell stack 101 and discharges the liquid water to the external environment, and the remaining gas enters the turbine 211 to apply work to the turbine 211, thereby preventing the liquid water discharged from the fuel cell stack 101 from damaging the turbine 211. Preferably, the outlet of gas-liquid separator 213 is in communication with the external environment via orifice 214.
Fig. 2 is a schematic structural view of a second embodiment of the air supply system of the fuel cell engine of the present invention, and as shown in fig. 2, the liquid outlet of the gas-liquid separator 213 is sequentially connected to a water storage tank 215 and a drain valve 216, and after the liquid separated by the gas-liquid separator 213 is drained to the water storage tank 215, the water storage tank 215 is controlled by the drain valve 216 to drain water, so that the water drainage can be controlled, and the liquid can be drained once at regular intervals, thereby preventing the gas-liquid separator 213 from continuously draining water.
