1. A power storage system comprising;

  • a unitary electrolytic and fuel cell having a solid oxide electrolyte, said cell being selectively operable to electrolyze steam to produce hydrogen and oxygen and to generate electric power;

    a steam feed system connected to said cell so as to deliver steam to said cell;

    a hydrogen store and an oxygen store connected to said cell so as to store hydrogen and oxygen produced by said cell, respectively, and so as to serve as a supply of hydrogen and oxygen for said cell;

    a heat-exchanger system connected to said cell so as to effect a heat exchange operation with said cell wherein heat of exhaust produced by said cell when generating electric power and when electrolyzing steam is transferred to said heat-exchanger system;

    a hot water feed system through which water is fed to effect space heating, said hot water feed system being connected to said heat-exchanger system such that water being fed through said hot water feed system is heated by said heat-exchanger system;

    an absorption refrigerating machine which uses heat to effect an absorption process, said refrigerating machine being connected to said heat-exchanger system so as to receive heat therefrom to effect said absorption process; and

    a cold water feed system through which water used for cooling a space is fed, said cold water feed system including a feed line connected to said refrigerating machine such that water being fed through said line is cooled by said refrigerating machine.
