Direct solid carbon fuel battery can be divided into polytype according to electrolyte difference, Solid Oxide Fuel Cell and the most temperature of molten carbonate fuel cell high, the conversion efficiency of electric energy is low, complex structure, and use barrier film, there is maintenance or replace the shortcomings such as difficulty.And adopt the solid carbon fuel battery of molten caustic soda electrolyte (electrolyte), there is the advantages such as temperature is low, battery efficiency is high, and structure is simple, easy to maintenance.
The late 19th century, the efficiency due to thermal power generation is low to 2.6%, and scientists, for raising the efficiency, is simplified energy conversion process and have developed DCFC technology.Within 1896, Jacques has built first DCFC model, utilize carbon electrode to record open circuit voltage higher than 1V, and maximum current density reaches 100mA/cm at 500 DEG C
2.Due to the accumulation of the electrolytical carbonating of alkali and residue, this system is caused to run continuously.
In DCFC, for alkaline electrolyte, as anode, there is oxidation reaction (reaction one), release electronics in solid carbon fuel; There is reduction reaction (reaction two) in oxygen, obtains electronics in the cathode; The transfer of electronics from anode to negative electrode provides electric energy, OH in electrolyte for the external world

In recent years due to global warming, acid rain and solid air particle increase the disposal of pollutants being all mainly attributed to thermal power plant, meanwhile, the technological development that energy efficiency only rests on about 35%, DCFC is brought into schedule.SRI, LLNL and SARA etc. of the U.S. take the lead in starting the scientific research of this respect.2010, the scholar from Australia, Britain and China also added R&D force.At present, DCFC technology is still in academic research and research and development of products stage, and technical research will constantly expand.Below representative research model is introduced.
In order to improve battery operating efficiency, reduce costs, in the urgent need to simple, Yi Zao, efficiently solid carbon fuel battery.
The fuel cell of fused carbonate is developed with the Lawrence National Laboratory of the U.S. (Lawrence Livermore NationalLaboratory (LLNL)) of Cooper leader.This battery adopts the fused carbonate of high temperature (800 DEG C) as electrolyte, and solid carbon particles is as fuel, and the oxygen in air is as cathodic reduction agent.Under the operating temperature of 800 DEG C, optimizing current density is 120mA/cm
2, power density is 60mW/cm
2.
Alkaline Direct Carbon Fuel Cells is developed in SARA company of the U.S. with the research and development group of Zecevic leader.Graphite carbon rod is used to fuel, and be immersed in the sodium hydroxide electrolyte of melting as plate conductor, oxygen is passed into by the dispersion pipe of battery bottom, and reacts with the cathode contacts as chamber wall simultaneously.Under the operating temperature of 630 DEG C, achieving optimization current density is 250mA/cm
2, power density is 57mW/cm
2.

2) there is chemical reaction generation carbon monoxide (CO).
C+CO
2＝CO
For alkaline electrolyte, with the raising of temperature, in gas, the content of carbon monoxide (CO) exponentially promotes, and such as, 800 DEG C time, has the gas componant of 89% to be CO, means solid carbon and the CO of 89%
2there occurs chemical reaction and consume.So, the carbon of consumption just cannot produce electronics, thus provides electric energy.600 DEG C time, the gas componant of 25% is CO.So, reduce the generating efficiency that temperature significantly will improve fuel.
For carbonate electrolyte, with the reduction of temperature, reaction speed reduces, and such as, 650 DEG C time, reaction can not occur.
