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 We know that a galvanic cell directly
converts chemical energy into electricity and is highly efficient It is
now possible to make such cells in which reactants are fed continuously
to the electrodes and products are removed continuously from the
electrolyte compartment
