Abstract: A capillary force-driven heat circulation system of a polymer electrolyte fuel cell is provided to allow circulation of a coolant through capillary force so that a polymer electrolyte fuel cell is cooled, to improve the cooling efficiency, and to avoid an additional energy consumption. A capillary force-driven heat circulation system of a polymer electrolyte fuel cell comprises: an evaporator(100) including a wick(110) for generating capillary force, a liquid coolant inlet, a vapor phase coolant outlet, and a vapor phase coolant conveying channel for conveying the vapor phase coolant from the wick to the outlet; a condensator(200) for condensing the vapor phase coolant evaporated through the heat exchange with a fuel cell in the evaporator; a coolant compensation chamber(300) including a first region next to the wick and a second region disposed inside the wick, occupying at least 50% of the total volume of a cooling device, and determining the driving temperature of the overall system by the internal saturated vapor pressure so as to stably supply the liquid coolant to the wick in which a direct phase change of the coolant occurs; and a coolant conveying line(400) for conveying the vaporized coolant to the condensator and the cooled liquid coolant to the evaporator, and extending to the second region inside the wick for the purpose of easy access of the liquid coolant to the internal part of the wick.
