<P> An electrochemical cell consists of two half - cells . Each half - cell consists of an electrode and an electrolyte . The two half - cells may use the same electrolyte , or they may use different electrolytes . The chemical reactions in the cell may involve the electrolyte , the electrodes , or an external substance ( as in fuel cells that may use hydrogen gas as a reactant ) . In a full electrochemical cell , species from one half - cell lose electrons ( oxidation ) to their electrode while species from the other half - cell gain electrons ( reduction ) from their electrode . </P>
