Description
Technical field
The invention patent relates to a kind of underwater chemical fuel cell power supplys, are with sea-bottom deposit nitride layer more particularly to one kind
The reactive metal fuel battery structure and device of electrolyte environment.
Background technique
Fuel cell is 21 century important clean efficiency power generation technology, and there are many kinds of fuel cells, including solid oxidation
Object fuel cell, molten carbonate fuel cell, phosphoric acid fuel cell, direct methanol fuel cell, pem fuel electricity
Pond etc..It wherein is also known as metal fuel battery by the fuel cell of fuel of metal, several light metals of aluminium, magnesium, zinc, lithium are because of its tool
The very high chemical activity having, is considered as ideal negative electrode material.But when due to electric discharge, there is hydrogen precipitation, be generally difficult to
Aqueous systems closed structure, and open cell structure is mostly used to design.This open cell structure can not only produce reaction
Outside object and waste heat discharge battery, seawater can also be introduced directly into and serve as electrolyte solution, and when seabed works, be not necessarily to resistance to compression
Shell designs convenient for structure.Therefore, using above-mentioned active metal or alloy as the seawater metal fuel battery (letter of negative electrode material
Claim seawater battery) be always underwater power source research hotspot.Seawater battery is during second of world war by U.S. Bell
Lab design, General Electric Co. Limited develop, it is provided by the corrosion dissolution of anode (cathode) metal material in the seawater
Discharge current, and cathode (anode) then relies primarily on dissolved oxygen of seawater and carries out reduction reaction offer yin on inert electrode
(in primary battery field, often electrode is referred to as positive and negative electrode to people to electrode current, and electrochemistry and electrolytic cell field, people's electrode are referred to as
Cathode and anode).The most prominent feature of seawater battery is not need to carry electrolyte, can utilize natural sea-water when needed
Form electrolyte.
Seawater battery is structurally characterized in that: metal negative electrode and conductive carbon material anode are placed in seawater electrolysis matter, are kept
One relatively-stationary distance, the cathode of seawater battery mainly provide electronics, and metal oxidation reaction occurs, and anode mainly occurs molten
Oxygen reduction reaction is solved, by taking magnesium as an example, positive and negative electrode reaction is as follows respectively:
Cathode: Mg-2e- →Mg2+, anode: O2+2H2O+e-→4OH-,
Seawater battery always exists a large amount of problems in engineer application.Such as: positive inorganic sediments passivation, according to
Above-mentioned positive and negative electrode reaction product, in battery During Process of Long-term Operation, magnesium ion is easy and hydroxide ion generates magnesium hydroxide and sinks
It forms sediment, positive electrode surface generates a large amount of inorganic sediments, and magnesium hydroxide is non-conductive, leads to positive failure；Equally, aluminium ion can also give birth to
At the cotton-shaped deposition of aluminium hydroxide, cathode performance is seriously affected.Another example is: metallic aluminium, magnesium anode material surface be under aerobic conditions,
Surface is readily generated passivating film (pellumina, magnesium oxide films), and pellumina is very stable, and cathode is caused seriously to be passivated, and influences
Metal ejected electron and battery performance.In another example magnesium metal, aluminium, zinc are very active, it is easy to happen evolving hydrogen reaction in the seawater, causes
Serious self-corrosion also easily causes serious chemical attack and electrochemical corrosion under ocean current souring, these are influenced
The stability of seawater battery service life and battery.
With the continuous development expanded with deep-sea detecting of mankind's ocean development range, underwater sensor, underwater robot
Equal instruments are the important equipments that people carry out ocean research, and the work of these instruments then needs continuous power drives, also,
Need to be distributed in far-reaching extra large position for monitoring environmental physics, chemokines variation.Many electronic instruments need continuous permanent worker
Make (up to the several years or longer), during desired work, once being exhausted using self-powered, they will be lost accordingly
Use function.Currently, people common several supply power mode (e.g., lead-acid accumulator, solar battery, high-energy lithium batteries
Pond, the on the bank cable transfer etc. of power supply) it cannot be long-term by influence factors such as subsea cryogenic, high pressure, weather, long transmission distances
Stablize and power supply is provided, it is difficult to meet the requirement detected for a long time at a distance.Still there is an urgent need to study underwater power supply with full
The demand of sufficient ocean development and detection.
