What is Concentration cell without transference?

A cell in which the transference of a substance from a system of high concentration to one at low concentration results in the production of electrical energy is called a concentration cell. It consists of two half cells having two identical electrodes and identical electrolytes but with different concentrations. EMF of this cell depends upon the difference of concentration. Concentration cell without transference is no direct transference of electrolyte but it occurs due to the result of the chemical reaction. Each electrode is reversible with respect to one of the ions of the electrolyte.
