Abstract
The invention discloses a chlorine-magnesium fuel cell, which comprises a cell body, a chlorine storage and gasification system and an electrolyte circulation and regeneration system, wherein the electrolyte circulation and regeneration system comprises a filter, an extraction stirrer, a water purifier, a standing device and an electrolyte storage tank, the outer side of the standing device is communicated with the electrolyte storage tank, and the outer side of the electrolyte storage tank is provided with a second power pump. A battery body of a chlorine-magnesium fuel battery comprises a battery shell and a chlorine channel, wherein a cathode membrane assembly is arranged inside the battery shell, a magnesium alloy anode plate is arranged inside the cathode membrane assembly, and a battery middle shaft is fixed in the middle of the inside of the battery shell. The chlorine-magnesium fuel cell takes the multielement magnesium alloy with excellent performance as the anode, the electrochemical conversion rate is high, the electrochemical reaction is uniform, and the current and voltage are stable; chlorine is used as an oxidant, so that the electrode potential is high, the cost is low, and the energy density is high.
Description
Technical field
The present invention relates to new fuel cell technical field, specially a kind of chlorine magnesium fuel cell.
Background technique
The energy is the important material base that human society is depended on for existence and development.And electric energy is as most important secondary energy
Source, with economic rapid development, demand of the mankind to electric energy is increasing, and which also promotes the transition and upgrades of electric energy industry.
Currently, in the market application it is most be lithium ion battery, because its self discharge is small, specific capacity is high, good cycle and environmental-friendly
The advantages that, it quickly grows, technology relative maturity.However lithium resource is limited on the earth, lithium ion battery higher cost, specific energy mistake
It is low, and there are safety issues, are unable to reach the requirement of pure electric automobile.
Magnesium is widely used as battery material, is the high-energy battery anode material for being only second to lithium.Compared with hydrogen fuel cell, magnesium
Fuel cell specific energy is high, safe and convenient to use, fuel is easy to storage and transportation, wide temperature range can be used, in addition magnesium rich reserves, no
It is only the second largest chemical element in one of the most abundant metallic element of content and seawater in the earth's crust, substantially reduces battery cost,
It has broad application prospects.
Since magnesium chemical property is active, activity is higher in neutral salt electrolysis matter, but using oxygen and hydrogen peroxide as
Oxidant can be reduced to hydroxide ion in neutral salt electrolyte by electrochemical catalysis, generate magnesium hydrate precipitate, lead to electricity
Pond failure, and the open-circuit voltage (electrode potential when no current flows through) of oxygen electrode is 0.4V more negative than its thermodynamic values, there is electric current
To occur serious polarization when flowing through, and micro cell can be caused to react because of surface impurity when ordinary magnesium alloy does anode in addition, that is, sent out
It is born from corrosion reaction, the practical open-circuit voltage of battery is caused to reduce, anode efficiency reduces, the lost of life.In addition, there are also magnesium-seas
Water dissolves oxygen fuel cell etc., but since the oxygen content dissolved in seawater is limited, this fuel cell efficiency is very low, is unable to satisfy
Big power battery needs.
Summary of the invention
The purpose of the present invention is to provide a kind of chlorine magnesium fuel cells, to solve the existing market that above-mentioned background technique proposes
Upper some battery higher costs, specific energy is too low, and there are safety issue, the short problems of service life.
To achieve the above object, the invention provides the following technical scheme: a kind of chlorine magnesium fuel cell, including battery body,
Chlorine gas storage gasification system and electrolyte indirect regeneration are connected with heat exchanger on the outside of the battery body, and heat is handed over
The outside setting of parallel operation is connected with storage chlorine tank, and the outside of the heat exchanger is connected by the first kinetic pump with filter, institute
It states and is connected with extraction blender on the outside of filter, and extract and be communicated with water purifier on the outside of blender and stand device, it is described
It stands and is communicated with anolyte storage tank on the outside of device, and the second kinetic pump is installed on the outside of anolyte storage tank.
