Problems solved by technology

And tested this type of battery with different scales, the output power density of small devices is very low, less than 2mW / cm2 2
The fluidized bed reactors in the above literature generally cannot effectively balance the solid phase residence time and reaction rate, and there are too many inner layers in the laminar flow layer, which cannot effectively increase the mass transfer rate

Abstract

The invention discloses a micron carbon fluid gaseous-phase bubbling device and a micron carbon fluid gaseous-phase bubbling method for direct carbon fuel cells. The micron carbon fluid gaseous-phase bubbling device and the micron carbon fluid gaseous-phase bubbling method have the advantages that turbulences are formed by a fluidized bed, an air distributor is arranged at an anode air inlet, carbon dioxide generated from a reaction between carbon and oxygen bubbles under the action of an anode gas circulation device and the air distributor, carbon particles gather on the surfaces of bubbles highly densely, local carbon concentration is increased, the bubbles are broken when contacting with an anode, laminar flow inner layers are eliminated, and the mass transfer velocity is increased to increase battery power density; carbon fuel microns are processed into the carbon particles, micron fluids are formed under the action of fluidized gases, and two dimensions of a direct electrochemistry reaction interface of carbon fuel are expanded into three dimensions, so that reaction interfaces and reaction frequencies of gas, liquid and solid phases are increased, mass transfer velocity is increased greatly, and power density in unit time and space is increased; a compound solution comprising three solutions serves as an electrolyte, so that physical property of the electrolyte is optimized and turbulence velocity of the electrolyte is reduced.

Description

technical field [0001] The invention relates to the field of direct carbon fuel cell preparation, in particular to a micron carbon fluid gas-phase bubble-making device and a bubble-making method for a direct carbon fuel cell. Background technique [0002] With the continuous and rapid development of my country's national economy, the clean and efficient use of energy has gradually become a very urgent issue. The traditional way of energy utilization is to first convert the chemical energy of the fuel into thermal energy, and then into mechanical energy and electrical energy. Due to the limitations of the Carnot cycle and materials, the power generation efficiency is only about 30%, and serious damage occurs during the power generation process. Waste water, waste gas, waste residue, waste heat and noise pollution. A fuel cell is a device that directly converts the chemical energy in fuel and oxidant into electrical energy. It is not limited by the Carnot cycle, and its power...
