Body inlet and outlet 39 and pressure controlling mouth 36 connect.
Below in conjunction with an operating process, the work step of above-mentioned battery is illustrated.
Firstly the need of opening hydrogen cylinder 1 and air compressor machine 9, proton exchange film fuel cell electric piling 12 is in hydrogen and air
It works under infeed, the pressure that hydrogen flows out fuel cell pack is P1, and the pressure that air flows into fuel cell pack is P2, works as P2
When > P1, the first auxiliary gas feed 20 connection and hydrogen outlet due to pressure regulator valve 8, the gas pressure of pressure regulator valve 8 incude mouth
22 connections and air outlet slit, therefore, the Hydrogen Vapor Pressure of the first auxiliary gas feed 20 of pressure regulator valve 8 are less than the gas sense of pressure regulator valve
The air pressure for answering mouth 22, since the effect of pressure is so that the first elastic diaphragm 25 is lifted up, while again due to pressure regulator valve 8
Therefore 35 connection of first gas outlet of second auxiliary gas feed 21 and aspirator 7 flows through the second auxiliary gas of pressure regulator valve 8
The hydrogen of body import 21 quickly through after pressure regulator valve 8 by exhaust outlet 23 flow out, then the auxiliary gas hydrogen of front end quickly through
35) aspirator 7(rapidly flows toward first gas outlet from the first gas import 34 of aspirator 7, due to the structure of aspirator 7
It is that radius big middle radius in both ends is small, fluid flows through aspirator 7, rapidly flows toward radius by the biggish first gas import 34 of radius
When lesser pressure controlling mouth 36, gas flow rate increases, then learns that pressure declines according to Bernoulli equation, resulting pressure
Drop can pressure controlling chamber 40 to counterbalance valve generate suction, because generating suction, suction in the pressure controlling mouth 36 of aspirator 7 at this time
The pressure controlling mouth 36 of gas device 7 is to connect with the auxiliary gas inlet and outlet 39 of counterbalance valve 9, and assist 39 He of gas inlet and outlet again
It is pressure controlling chamber 40 between second elastic diaphragm 53, the second elastic diaphragm 53 lifts, so that second gas import 37 and
Channel between two gas vents 38 is opened, and air is flowed to the gas vent heel row of counterbalance valve by the gas feed of counterbalance valve 13
Sky, then P2 is gradually reduced, until P2=P1；
As P2 < P1, i.e. the Hydrogen Vapor Pressure of the first auxiliary gas feed 20 of pressure regulator valve 8 is greater than the gas sensing mouth of pressure regulator valve 8
When 22 air pressure, since spring 24 downwards compresses the first elastic diaphragm 25, so that connecting rod 26 blocks sealing-plug 27
Aperture on partition 29, the hydrogen for flowing through the second auxiliary gas feed 21 of pressure regulator valve 8 cannot by the exhaust outlet of pressure regulator valve 8
23 outflows, that is, the flowing for flowing through the hydrogen of the second auxiliary gas feed 21 of pressure regulator valve 8 receive limitation, then the auxiliary gas of front end
Hydrogen is also restrained by the gas vent 35 that the first gas import 34 of aspirator 7 flows to aspirator 7, flows through aspirator 7
The hydrogen of first gas import 34 is then directly entered in the pressure controlling chamber 40 of counterbalance valve 13, counterbalance valve 13 second elasticity every
Film 53 pushes, and gas is restricted by the second gas outlet 38 that the second gas import 37 of counterbalance valve 13 flows to counterbalance valve 13,
Then P2 is gradually increased, until P2=P1；
As P2=P1, the diaphragm of counterbalance valve 13 maintains certain position, and air empties after continuing to flow through counterbalance valve 13, from
The hydrogen that gas-liquid separator 6 flows out is back to fuel after constantly flowing to second one-way valve 5 after aspirator 7 and pressure regulator valve 8
Battery pile.
By above pressure self-adjusting section process, so that the operation that whole system is stable.
The theoretical electromotive force of the monocell of fuel cell pack be 1.23V, and in actual moving process monocell specified electricity
It is pressed between 0.6-0.7V, remaining energy is converted into heat.Therefore, converting electric energy for this partial heat is to improve fuel
One of most efficient method of generating efficiency of battery system.
