    摘要: A fuel cell power generator having an output controlling system for preventing the deterioration of the fuel cell performance caused by fuel gas shortages. The fuel cell power generator includes a fuel reformer, a fuel cell, an inverter, and an output controlling system. The output controlling system includes an output control regulator for controlling the output power of the inverter as close to the current value corresponding to the output power set value as possible, a current command computing unit, an inverter controller, and an output correction section. The output correction section includes an available output computing unit for computing the maximum available output power value of the fuel cell on the basis of the detected flow rate of fuel gas flowing into the fuel cell or fuel exhaust gas flowing out of the fuel cell; a low level selector for selecting either the computed maximum available output power value or the output power set value, whichever is the lower; and an output correction regulator for supplying the output control regulator with a signal for correcting the output power set value so as to control the detected output current from the fuel cell as close to the current value corresponding to the output current value of the low level selector as possible.

    摘要: A rod-form high-purity polycrystalline silicon capable of preventing defects from occurring to a newly deposited silicon layer. To this end, a method of producing a rod-form high-purity polycrystalline silicon, depositing silicon on a rod-form silicon core by a thermal decomposition of a silane gas includes the steps of coating the rod-form silicon core to be used with a specific silicon layer by previously depositing any one kind of silicon layer of an amorphous silicon layer and a polycrystalline silicon layer made up of fine particles of silicon with different crystal axes from one another on a surface of the rod-form silicon core to be used by vapor growth, and depositing polycrystalline silicon by using the core coated with the specific silicon layer.
