Abstract:
A fuel reformer including a first pipe, a second pipe which is disposed in the first pipe, a main heat source, which includes an oxidation catalyst, filling the second pipe adapted to generate thermal energy with a predetermined temperature range through an oxidation reaction of a fuel using the oxidation catalyst; an auxiliary heat source which includes a torch connected to the second pipe to ignite and burn the gaseous fuel, thereby preheating the oxidation catalyst to within a reaction starting temperature range, and a reforming reaction unit which includes a reforming catalyst filling a space between the first and second pipes to generate a reforming gas containing hydrogen through the reforming reaction of the fuel using the reforming catalyst by using the thermal energy generated by the main heat source.
Abstract:
A fuel reforming apparatus in constructed with a main body including a first pipe and a second pipe disposed in the first pipe and a heat source installed in the second pipe and adapted to generate thermal energy in the second pipe. A reforming reaction unit is formed by filling a reforming catalyst in a space defined between the first and second pipes and is adapted to generate a reformed gas containing hydrogen through a reforming reaction of the fuel. A housing encloses the main body and allows a combustion gas generated from the heat source to flow along an outer circumference of the reforming reaction unit.
Abstract:
A power line layout of a macro cell includes power lines arranged on a plane of the macro cell in a diagonal direction. A combined layout of a macro cell and a power mesh includes a power mesh on which first power lines are formed in a vertical direction and a macro cell having internal circuit elements on which second power lines for providing a power voltage to the plurality of internal circuit elements are formed in a diagonal direction. The first power lines are electrically coupled to the second power lines at intersections between the first and second power lines when the macro cell is arranged to overlap with the power mesh. Accordingly, when the power lines of the macro cell are combined with the power lines of the power mesh, the intersections between the power lines of the macro cell and the power mesh may be easily formed.
