Abstract: The present invention relates to a concentration difference power generation apparatus with high efficiency, which can increase power generation efficiency by arranging an ion exchange membrane which increases charge transport. The present invention includes a flow oxidation electrode through which an electrode cleaning solution moves; a flow reduction electrode spaced apart from the flow oxidation electrode to face the flow oxidation electrode, and through which the electrode cleaning solution moves; and at least one pair of concentration difference paths disposed between the flow oxidation electrode and the flow reduction electrode, and having a fresh water path disposed in a direction close to the flow oxidation electrode, through which fresh water flows, and a salt water path separated from the fresh water path by an anion exchange membrane, through which salt water flows, with the pair of concentration difference flows being divided by the anion exchange membranes disposed at both ends. The electrode cleaning solution of the flow oxidation electrode and the flow reduction electrode circulates in a closed loop, and cations of the electrode cleaning solution are equal to cations of the salt water. Permeability of the water of the anion exchange membrane which is contact with the flow oxidation electrode and the flow reduction electrode is lower than that of the water of the other ion exchange members.
