ABSTRACT:
Disclosed herein is a structure for incorporating a fuel cell comprising a plurality of layers of unit cells which constitute a fuel cell which are elastically stacked between a fastening member and a base plate, the substantially entire surface of at least one of the end layers being pressed by the surface of a pressing jig wherein the other portion of the jig is rotatably engaged with the surface of the fastening member.
Also disclosed is a structure for incorporating a fuel cell comprising a plurality of layers of unit cells which constitute a fuel cell and are alternately stacked with partition plates placed on a base plate; a pressing jig having a spherical projection on the upper central portion placed on the stacked layers; and a fastening member having at its lower central portion a rounded concave engaged with the spherical projection of the pressing jig; the piled cells being fastened by means of bolts and nuts at the four corners of the fastening member and at the four corners of the base plate, and the nuts screwed to the bolts through pressing springs placed between the nuts and the upper surface of the fastening plate.
According to the structures of the present invention, the unit cells of the fuel cells can be held together with constant adherence even if uneven external forces are applied to the structure because of the presence of the rotatable upper portion or of the spherical projection of the jig whereby the air-tightness and the output can be maintained constant.
