A de-mineralizer for a fuel cell includes a cartridge assembly including an external outer cartridge and an internal inner cartridge installed inside a housing filled with ion resin, wherein at least one of the inner cartridge and the outer cartridge includes an etching network formed with a plurality of fine holes, in which at least one of a size and distribution of the fine holes are formed differently depending on the respective positions based on a vertical flow direction of the cooling water, and a frame formed on an outer circumferential surface of the etching network to support the etching network.

De-mineralizer for fuel cell and manufacturing method of same

A canned motor pump that includes a pipe-shaped can part which accommodates a rotor, a plurality of supports protruding radially outward from sides of the can part, and a plurality of the split cores each of which is inserted inside a corresponding support of the supports. Each distal end of the split cores extends in a direction toward a corresponding insulator part. A plurality of insulator parts are respectively formed on distal ends of the supports. An annular outer ring surrounds the outer circumference of the insulator parts. The inner circumference of the outer ring adjoins to exposed outermost ends of the split cores. Coils then are wound on the supports to provide a can motor pump with fewer parts and better performance.

Canned-motor pump for vehicle

A canned motor pump is provided that includes a rotor of a motor and a shaft shaped as a bar. The shaft penetrates through and is coupled with the rotor. A bearing is shaped as a circular cylinder, and is coupled to an upper side of the rotor. Further, the shaft penetrates through the bearing. A housing surrounds the rotor and the bearing to expose an upper end of the bearing and to house the rotor and the bearing within the housing.

A canned motor pump includes a stator assembly and a housing surrounding the outer portion of the state assembly. The housing is coupled with the stator assembly in a state in which the housing is divided into a plurality of pieces by cutting lines, and has a through-hole in a side portion into which a fastener is fastened. A fixing ring is coupled to the inside of the housing and the stator assembly so as to provide a seal between the housing and the stator assembly.

A cooling apparatus for a fuel cell is provided. The cooling apparatus for a fuel cell includes a reservoir that is configured to store a coolant and an ion filter assembly that is integrally installed at the reservoir and configured to remove bubbles in the coolant.

Cooling apparatus for fuel cell

The present invention provides a heating control method for a fuel cell vehicle, in which an additional heating source is used together with a typical electric heater to reduce power consumption and increase fuel efficiency as compared to the sole use of the electric heater. For this purpose, the present invention provides a heating control method for a fuel cell vehicle which comprises an electric heater for heating air supplied to the interior of the vehicle, and a heater core provided in a coolant line for cooling a fuel cell stack and heating the air supplied to the interior of the vehicle by heat exchange with the coolant discharged from the fuel cell stack. The method comprises: detecting a state of charge (SOC) of a battery when the interior temperature is lower than a predetermined temperature set by a driver and, if the SOC of the battery is above a predetermined lower limit, heating the interior of the vehicle by operating the electric heater by the power of a battery; heating the interior of the vehicle by operating the electric heater by the power generated by the fuel cell stack, if the SOC of the battery is below the lower limit; heating the interior of the vehicle using both the heater core and the electric heater, if the temperature of the coolant is above a predetermined temperature at which the fuel cell stack does not reach a normal operating temperature; and heating the interior of the vehicle using only the heater core while turning off the electric heater, if the temperature of the coolant is increased above a normal operating temperature of the fuel cell stack.

Heating control method for fuel cell vehicle

Disclosed is a canned motor for restraining a cogging torque from being generated by inserting magnetic metal pins into slot openings of a stator, thereby reducing noise and vibrations during an operation of the canned motor. The canned motor includes: a can inserted into a housing to seal a coil mounted within the housing; and a stator installed on an outer peripheral surface of the can and inserted along an inner peripheral surface of the housing. A plurality of fixing guides protrude from an outer peripheral surface of the can and metal pins are inserted into the fixing guides to be integral with the fixing guide, such that the metal pins are inserted into and attached to slot openings of the stator when inserted into the stator.

Canned motor for reducing cogging torque

An electric pump for a vehicle includes a pump body that is divided into a motor room and a pump room, a shaft that is connected to the motor room and the pump room and a sealing unit is interposed therebetween, and an impeller that is mounted on the shaft in the pump room. More specifically, a leachate exhaust passage for exhausting leachate that is leaked through the sealing unit is formed in the pump body, and the leachate exhaust passage is connected to a reaction gas exhaust portion of a fuel cell stack to aide in the exhaust of the leachate accordingly.
