Abstract: A fuel cell reformer includes a main body having a first pipe with a second pipe inside the first pipe, a thermal source unit in the second pipe, a reforming reaction unit in a first region between the first pipe and the second pipe to generate a reforming gas containing hydrogen through a reforming reaction of a fuel, and a carbon monoxide reduction unit in a region other than the first region between the first pipe and the second pipe to reduce a concentration of carbon monoxide contained in the reforming gas. A thermal treatment unit in the main body supplies thermal energy to the reforming reaction unit and the carbon monoxide reduction unit at a time of initial driving of the reformer such that the supplied thermal energy corresponds to a unique operational temperature range in the reforming reaction unit, and to a unique operational temperature range in the carbon monoxide reduction unit.

Abstract: A reformer includes a first body, a second body which is disposed in an inner portion of the first body, a heat source unit which is disposed in an inner portion of the second body to generate heat, a reforming reaction unit which includes a reforming catalyst placed in a space between first and second bodies to generate a hydrogen-rich gas from the fuel through a reforming reaction using the reforming catalyst, and a nozzle member which is disposed in the second body to distribute the fuel and the oxygen to the heat source unit.

Abstract: A system for adaptive partitioning of circuit components during simulating of a circuit having a hierarchical data structure includes a simulator module having one or more computer programs for 1) selecting a group of leaf circuits from the first branch and the second branch for simulation, where each leaf circuit is represented by a matrix comprising a set of equations, 2) determining a strength of coupling between two or more leaf circuits of the group in accordance with a set of predetermined electrical coupling criteria, 3) if two or more leaf circuits are deemed be strongly coupled, combining the corresponding matrix of each strongly coupled leaf circuit into a combined matrix, and 4) performing computation for the two or more strongly coupled leaf circuits in accordance with the combined matrix. The system adaptively adjusts the group circuit matrix for computing a group of circuits according to the strength of coupling between the circuits.
