Abstract

The invention provides a high power density molten carbonate direct coal / carbon fuel cell, comprising a battery body and a heating furnace for heating the battery body, a working electrode, a counter electrode and a reference electrode are installed in the battery body, the The working electrode includes an anode chamber, a pick-and-place rod is inserted into the anode chamber, and a flow hole is opened on the anode chamber to communicate with the electrolyte in the inner cavity of the battery. The anode chamber is filled with coal / carbon fuel, and the coal / carbon fuel A current collector is buried, and the current collector is led out through a high-temperature resistant insulated wire; the composition of the coal / carbon fuel includes at least transition metal oxide and carbon powder. The invention adds certain transition metal oxides to the anode chamber to act as a catalyst, effectively promotes the electro-oxidation reaction of the anode, improves the performance of the anode, and further effectively improves the power density of the fuel cell.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a high power density molten carbonate direct coal / carbon fuel cell. Background technique [0002] Coal occupies a dominant position in my country's energy structure, and this situation will not change for a long time. The efficiency of traditional coal-fired power plants is only 30-45%, and it emits a lot of greenhouse gases and pollutants such as SO 2 , NO x , particulate matter, etc. The direct coal / carbon fuel cell (Direct Coal / Carbon FuelCell, DCFC) can directly convert the chemical energy in coal / carbon into electrical energy, and the energy conversion efficiency is nearly doubled, which can greatly reduce energy loss and pollutant emissions. High purity CO can also be obtained 2 , easy to store and use. [0003] At present, there are not many patents related to MC-DCFC. The existing domestic related patents mainly focus on the following aspects: [0004] (1) MC-DCF...
