In some embodiments, the cooling water conditioning modules 500 and the gas conditioning modules 700 and the tail row modules 400 are distributed sequentially in the circumferential direction of the stack 300. Specifically, as shown in fig. 2, the cooling water regulating module 500, the gas regulating module 700 and the tail gas regulating module respectively flow through the stack 300 and are sequentially distributed in the circumferential direction of the stack 300, that is, the gas flow path and the cooling water flow path in the stack 300 structure can be sequentially arranged at intervals to form two loops separately, thereby realizing respective functions.
In some embodiments, the fuel cell testing system 100, further comprises: the first control valve 16 is provided with a first input port 161, a heating port 162 and a first output port 163, the first input port 161 is communicated with the heating outlet 121, the heating port 162 is communicated with the first heat exchanger 14, the first output port 163 is communicated with the output pipeline 13, the second control valve 17 is provided with a second input port 171, a cooling port 172 and a second output port 173, the second input port 171 is communicated with the cooling outlet 122, the cooling port 172 is communicated with the second heat exchanger 15, and the second output port 173 is communicated with the output pipeline 13.
Therefore, as shown in fig. 1, after the high-pressure anode/cathode gas flows out through the heating outlet 121 of the vortex tube 12, the high-pressure anode/cathode gas enters the first control valve 16 through the first input port 161 and then can be divided into two paths, one path flows from the heating port 162 to the first heat exchanger 14, and the other path flows from the first output port 163 to the output pipeline 13, so that the external component can be heated by the first heat exchanger 14, or the hot gas flow is directly output from the output pipeline 13 to the gas conditioning module 700. The first control valve 16 can distribute and adjust the flow rates at the heating port 162 and the first output port 163, for example, when the first heat exchanger 14 requires relatively more heating effects, the flow rate of the hot air flow output from the heating port 162 can be increased, and vice versa, so as to flexibly distribute the flow rate of the hot air flow and adjust the flow direction of the hot air flow according to the actual heating requirements, thereby satisfying different heating requirements.
Similarly, when the high-pressure anode/cathode gas flows out through the cooling outlet 122 of the vortex tube 12, the high-pressure anode/cathode gas enters the second control valve 17 through the second input port 171 and then can be divided into two paths, one path flows from the cooling port 172 to the second heat exchanger 15, and the other path flows from the second output port 173 to the output pipeline 13, so that external components can be cooled by the second heat exchanger 15, or a cold gas flow is directly output from the output pipeline 13 and enters the gas conditioning module 700. The second control valve 17 can distribute and adjust the flow rates at the refrigeration port 172 and the second output port 173, for example, when the refrigeration effect required by the second heat exchanger 15 is relatively more, the flow rate of the cold airflow output by the refrigeration port 172 can be increased, and conversely, the flow rate of the cold airflow output by the refrigeration port 172 can be decreased, so that the flow rate of the cold airflow can be flexibly distributed and the flow direction of the cold airflow can be adjusted according to the actual refrigeration requirement, thereby meeting different refrigeration requirements.
Therefore, the first control valve 16 and the second control valve 17 are arranged in the vortex temperature control device 1, and the heating and refrigerating treatment of the cathode/anode gas can be realized through the self regulation and heat exchange requirements, so that the temperature of the gas entering the gas regulation module 700 and the electric pile 300 reaches the requirement of the electrochemical reaction.

Thus, as shown in fig. 1, in the heating circuit, the mixed gas in the ejector 11 flows from the gas outlet 114 to the gas flow inlet 124, and enters the vortex tube 12 from the gas flow inlet 124, the hot gas flow separated from the vortex tube 12 flows from the heating outlet 121 to the first input port 161 of the first control valve 16, and is output from the first control valve 16 to the first heat exchanger 14 through the heating port 162, and the gas heated in the first heat exchanger 14 flows back to the ejector 11 from the first return port 112 and is mixed into the mixed gas again.
And, as shown in fig. 1, in the refrigeration circuit, the mixed gas in the ejector 11 flows from the gas outlet 114 to the gas flow inlet 124, and enters the vortex tube 12 from the gas flow inlet 124, the cold gas flow separated from the vortex tube 12 flows from the refrigeration outlet 122 to the second input port 171 of the second control valve 17, and is output from the second control valve 17 to the second heat exchanger 15 through the refrigeration port 172, and the gas refrigerated in the second heat exchanger 15 flows back to the ejector 11 from the second gas return port 113 and is mixed into the mixed gas again.
Therefore, the functions of heating and refrigerating can be respectively realized, the structure is simple, and the connection is convenient.
