Among the numerous modern, high-efficiency energy technologies allowing for the conversion of chemical energy of coal into electricity and heat, the Direct Carbon Fuel Cells (DCFC) deserve special attention. These are devices that allow, as the only one among all types of fuel cells, to directly convert the chemical energy contained in solid fuel (...

... coke, etc.) and oxygen (pure or contained in atmospheric air), while the products are: electrical energy, pure stream of carbon dioxide, and mineral residue. The coal fuel is intro- duced into the anode space of the cell and in the electrochemical reaction, carried out at elevated temperature, oxidizes to CO 2 , generating electric current ( Fig. 1). Currently used around the world are the DCFC-type cells which differ one another primarily by the type of electrolyte used. The type of electrolyte determines both the configuration of the device itself and the temperature of its operation. There are used four basic types of electrolytes: molten carbonates, oxygen-stable ceramic ...

... as a result of the carried out preliminary tests and modifications, there was manufac- tured a nickel model (prototype III, fig. 10), characterized by work stability and repeatability of electrical parameters measurements (unaffected by corrosive processes) under the same con- ditions at successive time intervals. During the works carried out so far, the research team has focused its efforts, among others, on checking the possibility of using different forms and ...

The article analyzes the current state of methods and means of monitoring air pollution in Ukraine. The issues of the formation of pollutants during the combustion of various types of fuel (gaseous, liquid, solid) in large power plants are considered. The data about the largest sources of air pollution in Ukraine are given. The main disadvantages o...
