ABSTRACT:
A water recovery system of a direct liquid feed fuel cell and a direct liquid feed fuel cell having the water recovery system. The water recovery system in which water produced at a cathode electrode of a membrane electrode assembly (MEA) is recovered to supply to an anode electrode, the water recovery system includes: a first member located on the cathode electrode and a first supporting plate that supports the first member; and a second member located on the anode electrode and a second supporting plate that supports the second member, wherein the first member and the second member are connected to each other through a slit formed in an electrolyte membrane of the MEA. The direct liquid feed fuel cell having the water recovery system can be used, for example, in a direct methanol fuel cell (DMFC).
