Abstract: A generator unit is installed locally to supply power to an electricity consumer. A management center monitors operation status of the generator unit and monitors the amount of electricity supplied to the electricity consumer by the generator unit. A service company performs maintenance and management for the generator unit based on instructions from the management center or the operation status of the generator unit. An electricity provider operating the generator unit bills the electricity consumer for an electricity supply service fee based on information sent to the management center. The resulting electricity generation equipment management system maintains and manages a generator unit without placing a burden on an electricity consumer, allowing efficient billing and payment of electricity supply service fees.

Abstract: Disclosed is a fuel cell power generating system which comprises a fuel cell unit having a coolant circulation system; a water storage tank for supply water to serve as coolant for the fuel cell unit; a water treatment system for purifying the supply water in the water storage tank and supplying the purified supply water as coolant to the fuel cell unit; heating means for heating water; a hot water storage tank for hot water acquired by the heating means; and a condensed-water supply system for supplying the water storage tank with condensed water obtained by condensing steam from the hot water in the hot water storage tank.

Abstract: A fuel cell generator system capable of reducing the process cost is described. The fuel cell generator system comprises a fuel cell including a cooling water circulation system, a water process system for processing water to supply as cooling water to the fuel cell, a heater for heating water by utilizing the heat generated in the fuel cell and a hot water storage vessel for storing the hot water from the heater, wherein the water process system is equipped with a water processing apparatus for removing impurities in the supply water and a concentrated water feed line for feeding to the hot water storage vessel, concentrated water in which the impurities are concentrated by the water processing apparatus.

Abstract: An apparatus 40 for water treatment has an electrodeionization device 34 to which power is supplied from a cell stack 30 of a fuel cell. The direct current power is transformed in its voltage by a transformer 35 and then supplied to the electrodeionization device without passing through an inverter. Efficiency of power supply is improved, and the apparatus is reduced in its equipments costs and a scale thereof. The apparatus 40 treats water from and relating to the fuel cell such as water produced by reaction of oxygen and hydrogen on the cathode, cooling water of the cell stack, water for steam fed to the reformer, and so on.
