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 ().

A vehicle position calculation apparatus and method are provided to correct a vehicle position to be located on a map route. The vehicle position calculation apparatus has a vehicle position measuring section measuring a vehicle position, a road data supply section supplying road geometrical data including a line segment and a closed region correlated with a road on a map, and a vehicle position correcting section correcting the vehicle position on the map by using the road geometrical data. The position correcting section locates the vehicle position by itself on the map as a corrected vehicle position, in response to a relatively positional relation between the vehicle position and the road geometrical data. In such a correction, the vehicle position correcting section can correct the vehicle position to be in alignment with a point on corresponding one of position correction shapes, or it can correct the vehicle position onto a traveling link generated in response to the road geometrical data.

A vehicle cruising control device has a vehicle-position/traveling-direction calculating circuit which receives data from a GPS signal receiver , a vehicle speed sensor , an angular-velocity sensor and a map data base to specify a road on which the vehicle is traveling and a road property gain circuit which gains a sort of road from the map data base , as road property. In the device, a driving force control unit controls a vehicle driving unit on the ground of the sort of road. If the map matching becomes to be improper, then the road property gain circuit operates to maintain the road property just before malfunction of the map matching until a traveling-distance after malfunction of the map matching reaches a predetermined distance. The traveling-distance is calculated by a traveling-distance calculating circuit
