20110250553 | Burner nozzle assembly and fuel reformer having the same - A burner nozzle assembly includes: a nozzle plate having an anode off-gas (AOG) nozzle at the center of the nozzle plate and a plurality of oxidation fuel nozzles surrounding the AOG nozzle; and a channel unit coupling the AOG nozzle with an AOG introducer to allow an AOG to flow therebetween and coupling the oxidation fuel nozzles with an oxidation fuel introducer to allow an oxidation fuel to flow therebetween. | 10-13-2011 |
20110273131 | FUEL CELL SYSTEM AND DRIVING METHOD THEREOF - A driving method of a fuel cell system, which includes a secondary battery and a fuel cell stack, is disclosed. The method includes detecting a state of charge (SOC) of the secondary battery, driving the fuel cell stack to an on-state whenever the SOC of the secondary battery is less than a predetermined first SOC, and driving the fuel cell stack to an off-state whenever the SOC of the secondary battery is greater than a predetermined second SOC. In this method, the fuel cell stack is driven at a fuel concentration having optimum efficiency, thereby increasing the fuel efficiency of the fuel cell system. | 11-10-2011 |
20110281188 | PREFERENTIAL OXIDATION REACTOR AND FUEL CELL SYSTEM USING THE SAME - A preferential oxidation reactor for removing carbon monoxide in a hydrogen mixture gas is disclosed. The preferential oxidation reactor may include a housing having a catalytic layer provided therein, a mixture gas supply portion inserted into the interior of the housing and penetrating the catalytic layer, a condensate receiving portion contained within the housing and in fluid communication with a gas outlet port of the mixture gas supply portion and condensate control tubes arranged in the catalytic layer of the housing and in fluid communication with the condensate receiving portion. The condensate control tubes may have a capillary structure. A fuel cell system including the preferential oxidation reactor is also disclosed. | 11-17-2011 |
20110281189 | CONNECTION STRUCTURE BETWEEN OXIDIZER AND FUEL VAPORIZER IN FUEL REFORMER AND METHOD FOR FORMING THE SAME - A connection structure between a fuel vaporizer and an oxidizer in a fuel reformer is disclosed. Fuel reformers having the connection structure may be included in fuel cell systems. Methods for forming the connection structure are also disclosed. The method includes forming the fuel vaporizer and forming the oxidizer. Forming the fuel vaporizer may include forming through-holes in a bottom panel and a top panel to form the fuel vaporizer, forming an inner side panel protruding in a direction substantially normal to a frame of the bottom panel through-hole and welding a top portion of the inner side panel to the frame of the top panel through-hole. Forming the oxidizer may include welding a top portion of an inner wall of the oxidizer to a bottom surface of the frame of the bottom panel through-hole. | 11-17-2011 |
20120115053 | FUEL CELL SYSTEM - A fuel cell system configured to prevent fuel cell freezing is disclosed. The fuel cell system includes a fuel cell, a reformer in fluid communication with the fuel cell, the reformer including a reactor and a heat feeding unit. A moisture supplying pipe is in fluid communication with the reformer and a reformer exhausting pipe is in fluid communication with the reformer. The reformer exhaust pipe is in fluid communication with the moisture supplying pipe and configured to pass high temperature gas discharged from the reformer exhaust pipe to the moisture supplying pipe. The fuel cell system may remove moisture in the fuel cell and may also prevent the moisture from freezing by using thermal energy generated during operation of the heat feeding unit. | 05-10-2012 |
20120219871 | FUEL CELL SYSTEM - A fuel cell system including: a fuel cell stack configured to generate electrical energy by a reaction of a fuel and an oxidant; a fuel supply configured to supply the fuel to the fuel cell stack; and an oxidant supply configured to supply the oxidant to the fuel cell stack, wherein the fuel supply includes a mixer including an inflow port, the mixer alternately receiving the fuel and water through the inflow port and being configured to mix the fuel and the water to generate a diluted fuel and supply the diluted fuel to the fuel cell stack. | 08-30-2012 |
