| 20080248373 | ANODE FOR FUEL CELL, MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL INCLUDING SAME, AND FUEL CELL SYSTEM INCLUDING SAME - Anodes for fuel cells, membrane-electrode assemblies for fuel cells including the anodes, and fuel cell systems including the membrane-electrode assemblies are provided. The anode includes a catalyst layer including a platinum-based metal catalyst and a carbon monoxide oxidizing catalyst on a catalyst support, and an electrode substrate. The catalyst support may be selected from ThO | 10-09-2008 |
| 20080268305 | FUEL REFORMING APPARATUS, AND FUEL CELL SYSTEM INCLUDING SAME - Fuel reforming apparatus and fuel cell systems including the same are provided. The fuel reforming apparatus includes a reactor main body; a catalyst reaction region inside the reactor main body for generating a reforming gas containing hydrogen by promoting at least a partial oxidation (POX) reaction of a reactant containing a hydrocarbon fuel and an oxidant; and a heat-insulating member inside the reactor main body surrounding the catalyst reaction region for insulating heat generated by the POX reaction. | 10-30-2008 |
| 20090110977 | FUEL CELL SYSTEM AND METHOD FOR OPERATING THE SAME - A fuel cell system and a method for operating the same are disclosed. In one embodiment, a fuel cell system includes a fuel supplier, a reformer for reforming a fuel supplied from the fuel supplier into hydrogen gas by a reforming reaction, and a fuel cell stack for generating electrical energy by an electrochemical reaction between the hydrogen gas and an oxidizing agent. When the fuel cell system is to be stopped, the reforming reaction of the reformer and the electrochemical reaction of the fuel cell are stopped and a portion of unreformed fuel is fed to the reformer and the fuel cell stack. Residual hydrogen is reacted and residual power from the fuel cell stack is dissipated by a power dissipation circuit. By largely removing hydrogen from the fuel cell stack on a stopped condition, reactions that are detrimental to the fuel cell membrane are reduced. | 04-30-2009 |
| 20090110978 | FUEL CELL SYSTEM - A fuel cell system that effectively processes a flue gas generated from a heat source of a fuel reforming apparatus. The fuel reforming apparatus generates a reforming gas containing hydrogen through a reformation reaction of the fuel from a fuel supply, and a fuel cell main body generates electrical energy through an electrochemical reaction of the reforming gas with an oxidizing agent. The fuel reforming apparatus includes a reforming reaction part and a heat source. The reforming reaction part induces a reforming reaction in the fuel, and the heat source provides heat energy to the reforming reaction part. A flue gas postprocessor induces an oxidation-reduction reaction in a flue gas exhausted by a combustion reaction of the heat source to decrease toxic ingredients, such as CO, hydrocarbons, and NO | 04-30-2009 |
| 20090110979 | FUEL REFORMING DEVICE AND FUEL CELL SYSTEM - A fuel reforming device that prevents a flash-back phenomenon includes a reforming reactor and a heater. The reforming reactor reforms a fuel, and the heater provides thermal energy to the reforming reactor by generating the thermal energy by a catalytic oxidation reaction between a catalytic layer and an oxidation reaction material. The heater includes an inflow pipe that receives the oxidation reaction material, an outflow pipe that outputs a flue gas generated by the catalytic oxidation reaction, and a flue gas retrieving pipe that connects the outflow pipe and the inflow pipe to direct the flue gas to the inflow pipe. | 04-30-2009 |
| 20110158860 | FUEL REFORMER - A fuel reformer is provided that is capable of improving endurance and performance. The fuel reformer includes a first burner having a first-burner first end, a first-burner second end, and a first opening formed in the first-burner first end; a second burner surrounding the first burner and having a second-burner second end, a second-burner second end, and a second opening in the second-burner first end, wherein the second-burner second end is coupled to the first-burner second end to communicate a fluid. The reforming reactor is configured to generate heat from the first and second burners, and has a fuel supply including a nozzle unit in the first burner and supplies a second oxidation fuel from the outside to the first burner. A first oxidation fuel is introduced into the first opening and flows through the first burner in a first direction and flows through the second burner in a third direction opposite to the first direction. The nozzle unit discharges the second oxidation fuel in a second direction crossing the first direction. | 06-30-2011 |
