ABSTRACT:
A fuel cell stack includes a cell assembly formed by stacking a plurality of fuel cells in a stacking direction. Terminal plates are provided outside opposite ends of the cell assembly in the stacking direction. An electrically conductive first heat insulation plate is interposed between one end of the cell assembly and the terminal plate, and an electrically conductive second heat insulation plate is interposed between the other end of the cell assembly and the terminal plate. The first and second heat insulation plates are metal corrugated plates. Heat insulation air chambers are defined between the first and second heat insulation plates and the cell assembly.
