Abstract:
1. A fuel cell comprising: a porous insulating film; a plurality of power generation units positioned on top of the porous insulating film, the plurality of power generation units including a pair of adjacent power generation units, said power generation units each including a first electrode facing said porous insulating film, a second electrode, and an electrolyte interposed between said first electrode and said second electrode, wherein a film having windows is laminated on said porous insulating film such that at least one of said first and second electrodes of said power generation units are disposed in said windows; a first electrically conductive film that is disposed between said pair of adjacent power generation units and is not stacked on either of said adjacent power generation units, said first electrically conductive film being electrically connected to said first electrode of one of said adjacent power generation units, and extending in parallel to said first electrode; and a second electrically conductive film that is disposed between said pair of adjacent power generation units and is not stacked on either of said adjacent power generation units, said second electrically conductive film being electrically connected to said second electrode of the other of said adjacent power generation units, and extending in parallel to said second electrode, wherein said first electrically conductive film and said second electrically conductive film are separate and distinct from said first electrode and said second electrode, wherein said first electrically conductive film or said second electrically conductive film has an expansion made of a same material as said first or second electrically conductive films, said expansion provided between said first electrically conductive film and said second electrically conductive film for connecting said first electrically conductive film and said second electrically conductive film, and wherein a portion of each electrolyte of the pair of adjacent power generation units is sandwiched between the first and second electrically conductive films.
