Portion, enters top, anode chamber the second pipeline 35 and flows back to electrolyte tank 31 after flowing through anode chamber.
In embodiment of the present utility model, blower fan 41 drives air or oxygen to enter the gas flow in battery pile 10, and then
Enter air electrode 81 Catalytic Layer by air electrode 81 gas diffusion layers and participate in electrochemical reaction.
It should be noted that the battery pile 10 shown in Fig. 4 can also use the electrolyte flow side in battery system shown in Fig. 2
Formula, i.e. electrolyte are driven pump 32 and the first pipeline 33 to flow into each battery list in battery pile 10 by electrolyte tank 31 through electrolyte
The top of the anode chamber of body 80, enters after flowing through anode chamber bottom anode chamber and flows back to electrolyte tank 31 through the second pipeline 35, sun
Electrolyte unnecessary in room, pole flows back to electrolyte tank 31 through electrolyte overfall 17 and the 3rd pipeline 37.
In shown in Fig. 3 and Fig. 4 two kind battery pile 10 structure, the anode chamber of each battery cell 80 can be that top is opened wide directly
Communicate with ambient atmosphere, it is also possible to arranging the hopper with a constant volume above anode chamber according to demand, the top of hopper is permissible
Use the mode of opening wide, communicate with ambient atmosphere, and this hopper can lay in a certain amount of metal fuel.It is understood that should be with
The metal fuel that the open ports that ambient atmosphere communicates is in the battery pile 10 shown in Fig. 1 and Fig. 2 adds mouth 11.
Fig. 5 is the fuel monitor mode schematic diagram of the battery pile of one embodiment of this utility model.As it is shown in figure 5, in bipolar plates
The upper fuel supervising device of installing of 93 (on the left of Fig. 5) or hopper 97 (on the right side of Fig. 5), the i.e. first fuel monitoring probe 23 and the
Two fuel monitoring probes 24, the resistance between the first fuel monitoring probe 23 and the second fuel monitoring probe 24 and metal therebetween
Fuel 84 is stacking bed relevant.
In an embodiment of the present utility model, when fuel supervising device detects that anode indoor metal fuel accumulation bed height is low
In or during equal to the first predeterminated position, metal fuel is not enough, and control unit 50 controls electronic fuel and adds mechanism 22 to anode chamber
Or the hopper above anode chamber adds metal fuel, when fuel supervising device detects that bed height piled up by anode indoor metal fuel
During greater than or equal to the second predeterminated position, metal fuel is sufficient, stops adding described metal fuel.
Specifically, the first fuel monitoring probe 23 and the second fuel monitoring probe 24 submergence in the electrolytic solution, when first fuel supervise
Full metal fuel, i.e. anode indoor metal fuel accumulation bed height is filled high between control probe 23 and the second fuel monitoring probe 24
In or equal to the second predeterminated position, during metal fuel abundance, the resistance between two fuel monitoring probes is first resistance R1,
Metal fuel is not had, i.e. anode indoor metal fuel assembly between the first fuel monitoring probe 23 and the second fuel monitoring probe 24
Long-pending bed height is less than or equal to the first predeterminated position, and during metal fuel deficiency, the resistance between two fuel monitoring probes is second
Resistance value R2；Resistance between the first fuel monitoring probe 23 and the second fuel monitoring probe 24 is absolute with the difference of R2
When value is less than setting value, control unit 50 controls to add in the electronic fuel interpolation mechanism 22 hopper above anode chamber or anode chamber
Adding metal fuel, the resistance between the first fuel monitoring probe 23 and the second fuel monitoring probe 24 is exhausted with the difference of R1
During to value less than setting value, stop adding metal fuel.It is appreciated that setting value can be approximately zero.
More specifically, in the work process of battery pile 10, the metal fuel 84 in anode chamber is constantly consumed, the first fuel
Resistance between monitoring probe 23 and the second fuel monitoring probe 24 increases along with the reduction of the stacking bed height of metal fuel 84,
When the stacking bed height of metal fuel 84 drops to the first fuel monitoring probe less than 23, the first fuel monitoring probe 23 He
Resistance between second fuel monitoring probe 24 increases to maximum, now control unit 50 to electronic fuel add mechanism 22 (see
Fig. 1 or Fig. 2) send instruction, start to add metal fuel 84 for battery pile 10.Along with the interpolation of metal fuel 84, first
Resistance between fuel monitoring probe 23 and the second fuel monitoring probe 24 along with the stacking bed height of metal fuel 84 increase and
Reduce, when the stacking bed height of metal fuel 84 reaches the height of the second fuel monitoring probe 24 position, the first fuel prison
Resistance between control probe 23 and the second fuel monitoring probe 24 minimizes, and now control unit 50 is added to electronic fuel
Mechanism 22 sends instruction, stops fuel and adds.
It should be noted that when installing the first fuel monitoring probe 23 and the second fuel monitoring probe 24 in bipolar plates 93,
Use the battery pile of embodiment illustrated in fig. 4；When installing the first fuel monitoring probe 23 and the monitoring spy of the second fuel on hopper 97
