20140120432 | BUBBLE REMOVING DEVICE FOR AN ION FILTER IN A FUEL CELL SYSTEM - Disclosed is a bubble removing device for an ion filter of a fuel cell system, in which bubbles generated from cooling water passing through an ion resin are discharged outside the ion filter and are easily removed. The bubble removing means may be installed in an ion filter located on a top portion in the fuel cell system, to thereby maximize the power efficiency and heat emission efficiency of the fuel cell system. | 05-01-2014 |
20140170515 | APPARATUS AND METHOD FOR CONTROLLING COOLANT TEMPERATURE OF FUEL CELL SYSTEM - Disclosed is an apparatus and method that controls a coolant temperature of a fuel cell system, which can improve fuel efficiency by performing a multi-point temperature control based on the power of a vehicle, the outdoor temperature for each season, etc. | 06-19-2014 |
20150183337 | TEMPERATURE MANAGEMENT SYSTEM OF FUEL CELL VEHICLE AND METHOD THEREOF - A temperature management system of a fuel cell vehicle includes a radiator, a water pump, an ion filter, a flow control valve, a state detector and a controller. The radiator is configured to emit heat generated from a fuel cell stack via cooling water, and the water pump is configured to circulate the cooling water through the system. Additionally, an ion filter is disposed in a branch line branched from a cooling water circulating line connecting the fuel cell stack and the radiator. The state detector is configured to detect cooling water state information and the flow control valve is configured to selectively interrupt a flow of the cooling water into the ion filter; and a controller configured to control an operation of the flow control valve depending on the cooling water state information detected by the state detector. | 07-02-2015 |
20150183338 | THERMAL MANAGEMENT SYSTEM FOR FUEL CELL VEHICLES - A thermal management system is provided which may be miniaturized and may have a reduced weight by integrating thermal management parts in a fuel cell vehicle. In particular, a new type of thermal management system integrated housing in which a housing of a pump housing part, a housing of a 3-way valve fluid part, and a bypass channel among parts of the thermal management system for a fuel cell vehicle are integrated into a single structure to reduce the size of the overall system. | 07-02-2015 |
20150184759 | VALVE FOR CONTROLLING COOLANT FUEL CELL STACK COOLANT OF FUEL CELL VEHICLE - A valve for controlling the temperature of a coolant to flow into a fuel cell stack to provide the optimum level of coolant at the appropriate temperature in order to keep the operation of the fuel cell stack stable is provided. In particular, new type of seal that can achieve maximum sealability with minimized friction force on a plunger shaft by changing the shape and structure of a seal for sealing the plunger shaft. As such, the valve provides a coolant control valve for a fuel cell stack in a fuel cell vehicle which can improve durability in addition to preventing water leakage and can contribute to reducing the manufacturing cost via reduction of the number or parts and simplification of the structure by removing peripheral parts all while sufficiently sealing the valve. | 07-02-2015 |
20150188156 | THERMAL MANAGEMENT SYSTEM AND METHOD FOR FUEL CELL VEHICLE - A thermal management system and method for a fuel cell vehicle is provided. c In particular, a radiator, a 3-way valve, a pump, a heater, and a stack are all connected in that order. The system is capable of selectively de-mineralizing and providing an increase in flow rate by connecting a de-mineralizer line to a port at a bypass line side of a 3-way valve. | 07-02-2015 |
