    摘要: The present invention provides a distributed secondary battery type power storage system capable of maintaining the soundness of the secondary battery and of efficient electric power charging and discharging operations. The secondary battery power storage system comprises a secondary battery connected to a load, a charge/discharge unit connectable to a power system and connected to the secondary battery, and a plurality of loads connected to the charge/discharge unit. A power receiving object is selected and a capacity is determined on the basis of information about the operating condition of the plurality of loads, and the surplus electric power remaining in the secondary battery after feeding electric power from the secondary battery to the load is fed to the selected power receiving object through the charge/discharge unit. The secondary battery power storage system is capable of maintaining the soundness of the secondary battery and of efficient charging and discharging operation.

    摘要: The polymer electrolyte type hydrogen-oxygen fuel cell of the present invention comprises an oxygen electrode (72, 73) and a hydrogen electrode (74), a polymer electrolyte membrane (71) provided between the oxygen electrode (72, 73) and hydrogen electrode (74) and electron conductors (75) provided on the side of the electrodes which is opposite to the electrolyte side and the oxygen electrode (72, 73) comprises a catalytically active component, a carrier for the catalytically active component and a binder and has such a gradient in water repellency across the thickness that the water repellency is highest in the area adjacent to the electrolyte (71) and lowest in the area adjacent to the conductor (75). In this fuel cell, flooding of water at the interface between the oxygen electrode (72, 73) and the electrolyte (71) can be prevented.
