Explanation: Fuel cells: Production of electricity by thermal plants is not a very efficient method and is a major source of pollution. In such plants, the chemical energy (heat of combustion) of fossil fuels (coal, gas, or oil) is first used for converting water into high-pressure steam. This is then used to run a turbine to produce electricity. ...
