1. A method of manufacturing a solid oxide fuel cell stack, the method comprising,
alternately disposing a plurality of single fuel cells, each having an anode layer, a cathode layer, and a solid electrolyte layer, and a plurality of interconnectors are disposed alternately and holding the alternately disposed plurality of single fuel cells and plurality of interconnectors between a pair of end members in a direction in which the plurality of single fuel cells face one another,
forming a space between a first end member and a first interconnector;
disposing a junction member composed of an elastic member and an electrically conductive member in the space;
with respect to the direction in which the plurality of single fuel cells face one another, disposing a portion of the electrically conductive member between the first end member and the elastic member to be in contact with at least the first end member, and disposing another portion of the electrically conductive member between the first interconnector and the elastic member to be in contact with at least the first interconnector;
electrically connecting the first end member and the first interconnector through the electrically conductive member;
wherein in a stacking direction, a second interconnector, the single fuel cell, the first interconnector, the junction member, and the first end member are disposed in order, and one and only one single fuel cell is disposed between the second interconnector and the first end member; and
urging the portion of the electrically conductive member and the another portion of the electrically member against the first end member and the first interconnector so that a total thickness of the portion of the electrically conductive member, the another portion of the electrically conductive member, and the elastic member prior to being disposed in the space between the first end member and the first interconnector is greater than a height of the space.
