    摘要: The present invention relates to an inverter and a lamp driver having the same. The inverter includes a first switch having a first body diode, a second switch having a second body diode, a transformer including a first side coil in which a first current and a first voltage are generated according to switching operations of the first switch and the second switch and a second side coil having a predetermined winding ratio with respect to the first side coil, and a controller for controlling each switching operation of the first switch and the second switch. The controller turns on one of the first switch and the second switch corresponding to one of the first body diode and the second body diode, and a current flows through the first switch and the second switch during a dead time.

    摘要: A reformer for a fuel cell system includes a reforming portion for converting fuel containing hydrogen into hydrogen-rich gas; and an adiabatic portion entirely covering the reforming portion, the adiabatic portion being composed of first and second adiabatic layers arranged opposing each other with at least one spacer interposed between the first and second adiabatic layers. As such, the fuel cell system has an effect of enhancing the adiabatic performance of a thermal reaction for producing reforming gas and distributing thermal residence stress uniformly on the surface of the reformer.

    摘要: A stack for a fuel cell system which can include a simplified fastening structure and a fuel cell system having the stack are shown. The stack includes at least one electricity generator, a housing, and a cover. The electricity generator includes a MEA and separators located on both surfaces of the MEA. The housing has an internal space in which the electricity generator is positioned, and a cover coupled to the housing to fix the electricity generator in place. A number of various mechanisms are shown for holding the housing and the cover together and for fixing the stacks in place. A number of reinforcing elements and structural shapes are also shown that yield a stronger housing and cover assembly that resists buckling and other forms of stress.
