The design for sealing anode electrode body changes the opening of conventional air oxygen metal fuel battery air, electrolyte sealing Working method, overcome leakage just and not can guarantee the problem of battery uses, new operating mode is: air, oxygen, oxygen source are close It seals and increases certain pressure, the speed for not only accelerating oxygen molecule flowing reactive can be sunk in electrolyte again, guarantee reaction chamber Gas concentration consistency, realize battery pile the operation is stable, safety, consistent requirement.

The strip-shaped hole of design is covered in battery pile, is both the injection hole of the filler port of cell stack fuel room and electrolyte, It is conveniently added with metal alloy fuel in sealed cell heap, and is convenient to take out the oxide after reaction, realizes metal Fuel-air, reliable, safety, does not disintegrate continuously and takes out the commercialization process of oxide at the convenience of oxygen metal fuel battery.

In conclusion air provided by the utility model, oxygen metal fuel battery realize the positive and negative of single battery body Catalytic air electrode slice is pasted on two sides, is formed oxygen source seal, is passed through oxygen, air or liquid oxygen source, then with negative electricity polar body The cooperation of frame boss, fastening are assembled into single battery body, and series-connected cell body forms battery pile and sinks in the electrolyte in battery case, lead to It crosses in parallel anode, cathode output Current Voltage, solves the problems, such as that electrolyte crossfire, decompression, short circuit can not work, realize High current, high capacity low temperature easily start the effect that high temperature can cool down, radiate, and battery is enable to be used in all-weather condition, and fuel Design on cathode frame solves the problems, such as fixed, control gap after fuel-cell fuel filling, ensure that metals capacity electricity Optimum response distance between pool cathode and anode.

Seal the structure of positive polar body by changing oxygen air liquid oxygen source electrode body, electrolyte is open to be shared, it is in parallel just, The frame mode of cathode has reached open circuit when large capacity, high current, electrolyte share, efficiency reduction cell body can still continue The advantage of work, burning voltage electric current can not be provided by so that metal fuel battery is overcome leakage crossfire, decompression, low temperature, high temperature etc. Critical defect.
