Problems solved by technology

However, SO-DCFC is currently not dominant in current density, and the reaction speed is relatively slow
The main reasons are (1) the contact surface between the fuel and the anode is limited to a two-dimensional plane, and the direct electrochemical reaction interface of carbon is limited; (2) the reaction rate of coal gasification limits the gas electrochemical reaction

Abstract

The invention discloses a conductor catalyst for enhancing the performance of a direct carbon fuel battery and a method, which relate to the technical field of cleaning energy. The conductor catalyst is prepared by mixing an ion conductor, an electronic conductor and a carbon gasification catalyst and then processing by a mechanical crushing method or a solid phase synthesizing method. The conductor catalyst provided by the invention is applied for generating power for the direct carbon fuel battery; a conductor network is formed in a battery anode; the direct electrochemical reaction of carbon is enlarged; the reaction speed of carbon gasification is enhanced through the carbon gasification catalyst; and the reaction speed of carbon gasification is enhanced.

Description

technical field [0001] The invention belongs to the technical field of clean energy, and in particular relates to a conductor catalyst and a method for improving the performance of a solid oxide direct carbon fuel cell. Background technique [0002] my country is the largest coal producer and consumer in the world, and its coal consumption accounts for more than 70% of the total primary energy, of which more than 50% of the coal is used for thermal power generation. At the same time, coal also occupies a major position in my country's power structure. The coal-based energy structure will not change much in a short period of time. However, at present, my country's coal-fired power generation efficiency is low, energy waste and environmental pollution are serious; at the same time, as the world's CO 2 As the largest emitter country, we are facing a huge CO 2 pressure to reduce emissions. Therefore, exploring efficient clean coal power generation technology is an inevitable...
