Separators (A,B,) and membrane-electrode assemblies () of a fuel cell stack () are alternately stacked in a guide box (). The separators (A,B,) each have groove-like gas paths (A,B). Powder of an adhesive agent () is adhered in advance to the surfaces of the separators (A,B,), except the gas paths (A,B), through photosensitive drums (A,B) to which the powder is adsorbed in a given pattern. The separators (A,B,) and the membrane-electrode assemblies (), stacked in the guide box (), are heated and compressed by a press () and heaters (C) to obtain a unitized fuel cell stack ().

Fuel cell and production of fuel cell stack

Unit cells are held in a plate frame to form a cell module. A plurality of the cell modules is laminated in a thickness direction of the frame to form a laminated structure of unit cells. The cell unit is pressurized with heat sinks from both sides in the direction of the lamination, and is integrally held to form a battery.
