ELECTRIC WATER PUMP FOR VEHICLE

摘要

PURPOSE: An electromotive water pump is provided to smoothly discharge leachate leaked from a pump chamber to a motor chamber because a leachate discharge passage is connected to a reactant gas discharging unit of a fuel cell stack through a connection pipe. CONSTITUTION: An electromotive water pump comprises a pump body(110), a shaft(140), and an impeller(150). The pump body is divided into a motor room(110) and pump room(120). The shaft is connected to the motor room and pump room with a sealing unit placed in the shaft. The impeller is inserted into the shaft in the pump room. A leachate discharge passage is formed in a pump body and discharges leachate leaking to the motor room through the sealing unit. The leachate exhaust path is connected to a reactant gas discharging unit(11) of a fuel cell stack(10).
