20110236775 | Fuel Cell System - A fuel cell system quickly and efficiently preheats a frozen stack. The fuel cell system includes: a reformer which generates a reformate gas by reforming a fuel and is heated by a heat source unit; a stack which generates electricity by electrochemically reacting an oxidizer with hydrogen in the reformate gas; and a fluid flow controller which moves air around the reformer into an area around the stack, and which controls airflow on the basis of a temperature change of the stack, wherein the air is heated by the surface temperature of the reformer. | 09-29-2011 |
20110236777 | FUEL CELL SYSTEM TO PREHEAT FUEL CELL STACK - A fuel cell system including: a reformer to convert a fuel into hydrogen; a reformer chamber to contain air heated by the reformer; a fuel cell stack to convert the hydrogen into electricity; a first pump to supply an oxidant to the stack; and a second pump to supply the heated air to the stack, to preheat the stack. The system may also include a controller to control the operation of the system, such that the heated air is not supplied until it reaches a predetermined temperature, and the oxidant is not supplied and the stack is not operated, until the stack reaches a predetermined temperature. | 09-29-2011 |
