FUEL RECOVERY DEVICE IN FUEL CELL

摘要

PURPOSE: Provided is a fuel recovery device in fuel cell which is suitable to reduce costs necessary to generate electricity, by recovering water wasted after generation and reusing the waste water. CONSTITUTION: The fuel cell comprises a stack(10) which comprises a cathode and an anode, and in which hydrogen gas supplied to the anode is electrochemically reacted with air supplied to the cathode to form electromotive force. The fuel cell has water recovery means(14) for recovering water through the discharge line(13) of the stack and reusing the water. The water recovery means(14) consists of a water recovery line for connecting the discharge line(13) and water tank(42) and recovering water in reaction byproduct discharged through the discharge line(13); and a pump(52) for water recovery, which is positioned on the means(14) and pumps the recovered water.
