摘要： An electric power control apparatus is for a fuel cell system including an impedance measurement unit that measures an impedance of the fuel cell based on a current and a voltage measured when alternating-current electric power is superimposed on output electric power of the fuel cell. A processor of the electric power control apparatus: estimates a remaining capacity of the electric power storage device after execution of a process of measuring the impedance; performs charging and discharging of the electric power storage device before start of the process of measuring the impedance, to make the estimated remaining capacity fall within a predetermined range from a lower limit value to an upper limit value; and controls electric power generation of the fuel cell to make a generated current of the fuel cell constant, during the execution of the process of measuring the impedance.

摘要： A power generation system having a gas turbine, a fuel cell, an exhaust air circulation line, an exhaust fuel gas supply line, a turbine, an exhaust heat recovery boiler, and at least one exhaust air heat exchanger. The turbine is equipped with a high-pressure turbine, a medium-pressure turbine, and a low-pressure turbine. The exhaust heat recovery boiler is equipped with a high-pressure steam circulation mechanism, a medium-pressure steam circulation mechanism, and a low-pressure steam circulation mechanism. The exhaust air heat exchanger exchanges heat between the steam exchanging heat with the exhaust gas in the high-pressure steam circulation mechanism or the medium-pressure steam circulation mechanism and flowing toward the turbine and the exhaust gas flowing through the exhaust air circulation line, thereby increasing the temperature of the steam and decreasing the temperature of the exhaust gas.

摘要： Invented is a Resource Tower that uses water electrolysis to separate out its elemental and purified H2 hydrogen gas and O2 oxygen gas. These gases form a pressurized flow for electricity generation for distribution and transport to heights atop the Resource Tower. Core advancements of this invention are the use of fuel cells at the top of the Resource Tower to electrochemically combine hydrogen gas and oxygen gas to produce electricity, heat, and water. The Resource Tower distributes the electricity, converts heat and water to steam to generate additional electricity for distribution, and ultimately coalesces the steam back to water at a height. The water that falls under acceleration of gravity from atop the Resource Tower is used to generate additional electricity for distribution. In addition to multiple sites of electricity generation for distribution, the purity of hydrogen gas and oxygen gas from water electrolysis is retained and the water resulting from the Resource Tower is purified and potable for distribution.
