1. A fuel cell system for directly convening chemical energy of a fuel into electrical energy by electrochemical means, the system comprising:

  • first means for storing hydrogen, said first means for storing hydrogen having a hydrogen-absorbing alloy for dissociating a hydrogen gas at a temperature from approximately -20°

    C. to room temperature;

    a fuel cell having a hydrogen electrode and an oxidizer electrode;

    means for supplying air to said oxidizer electrode at least when said system starts operating;

    said fuel cell including means for generating electricity from hydrogen supplied to said hydrogen electrode from said first means storing hydrogen and from oxygen supplied from a vicinity of said oxidizer electrode;

    first means for supplying an amount of an oxidizer gas to said oxidizer electrode;

    said first means for supplying being driven by an output from said fuel cell;

    second means for supplying an amount of hydrogen to said hydrogen electrode;

    said second means for supplying including means for connecting said first means for storing hydrogen and said hydrogen electrode; and

    said second means for supplying being driven by an output from said fuel cell.
