Abstract
A dummy cell disposed at least at one end of a cell stack body in a fuel cell stack includes a dummy electrode assembly. The dummy electrode assembly includes a plate, and a pair of electrodes joined to both surfaces of the plate through adhesive layers, respectively. The adhesive layers are disposed only in a second area that lies outside a first area corresponding to a power generation area of a power generation cell in the dummy electrode assembly.
Claims14
A dummy electrode assembly having no power generation function, the dummy electrode assembly being used instead of a membrane electrode assembly, in a dummy cell, the dummy cell being disposed at least at one end of a cell stack body in a fuel cell stack, the cell stack body comprising a plurality of power generation cells that are stacked together in a stacking direction,
- the dummy electrode assembly comprising:
- an electrically conductive plate used instead of an electrolyte membrane;
- and
- a pair of electrodes joined to both surfaces of the plate through adhesive layers, respectively, the pair of electrodes having different sizes in a plan view,
- wherein the adhesive layers are disposed only in a second area that lies outside a first area corresponding to a power generation area of the power generation cell, in the dummy electrode assembly.
