Abstract

The invention provides a molten carbonate direct coal / carbon fuel cell with high power density. The fuel cell comprises a battery body and a heating furnace for heating the battery body, and a workingelectrode, a counter electrode and a reference electrode are arranged in the battery body; the working electrode comprises an anode chamber, a pick-and-place rod is inserted into the anode chamber, acirculation hole communicated with electrolyte in an inner cavity of the battery body is formed in the anode chamber, the anode chamber is filled with coal / carbon fuel, a current collector is buriedin the coal / carbon fuel, and the current collector is led out through a high-temperature-resistant insulated wire; the components of the coal / carbon fuel at least comprise transition metal oxide and carbon powder. According to the invention, a certain transition metal oxide is added into the anode chamber to play a role of a catalyst, so that the electrooxidation reaction of the anode is effectively promoted, the anode performance is improved, and the power density of the fuel cell is further effectively improved.

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...
