Problems solved by technology

[0003] However, we can see from the above information that there are two major deficiencies in the current research on direct carbon fuel cells: 1) the implementation temperature is too high
2) low power
Per capita remaining recoverable oil and natural gas is only 7.7% and 7.1% of the world average! On the other hand, the energy waste is astonishing, and the utilization rate is only 33%, which is 10% lower than the international advanced level

Embodiment Construction

[0022] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0023] The direct carbon fuel cell is a powder-molded button cell, the electrolyte 3 is in the middle, and the two sides are the anode 1 and the cathode 2 respectively. mm, the thickness range can be 1-2 mm, see Figure 1.

[0024] Examples 1-36 are detailed descriptions of the performance of direct carbon fuel cells in which various carbon materials are used as anodes. See Table 1 for specific anode materials, fuel cell performance, and temperature experimental data.

[0025] (1) The performance of carbon anode material fuel cells (see Table 1), mainly divided into the following categories:

[0026] 1. Performance of biomass-derived direct anode material carbon fuel cells

[0027] 1) Several chemicals activated carbon C: atomic weight: 12.01, analytically pure

[0028] C1 activated carbon (fine granular) Shanghai Sinopharm Chemical Reagent Co...

Abstract

The invention relates to a direct carbon fuel cell, which provides a direct carbon fuel cell directly taking carbon or carbon composite as the anode, and metal oxide as the cathode, single or double phase low medium temperature ceria composite as the electrolyte. The direct carbon fuel cell is power molding button cell with electrolyte in the middle and the anode and cathode separately on each side. The pressed sheets of anode and cathode are one to two mm thick. The invention can get the best performance about 0.25 watts per square centimeter under the temperature of 600 to 650 degrees centigrade, which is two times above the performance of such fuel cell according to a report from USA and has reached the international leading level.

Description

technical field [0001] The present invention directly uses carbon as a direct carbon fuel cell. Background technique [0002] Hubei Institute of Science and Technology Information, Hubei Productivity Promotion Center, Wuhan Documentation and Information Center of Chinese Academy of Sciences, "Intelligence and Decision - Dynamic Monitoring of High-tech Development" Issue 11 special report on November 25, 2005: "The American research institution SRI International is Develop a Direct Carbon Fuel Cell (DCFC) technology...that converts the chemical energy stored in coal directly into electricity without gasification. It is twice as fuel efficient as current coal-fired power plants, reducing CO2 emissions. It can also generate electricity from a variety of fuels such as coal, coke, tar, biomass and organic waste at competitive costs. The company said. "This one-step, clean and efficient energy conversion process, through carbon Electrochemical oxidation converts the chemical ener...
