Systems and methods produce or provide a folded connection, sealed by means of an adhesive composition, between a first sheetlike element and a second sheetlike element. The systems and methods bond a second flange of the second sheetlike element with at least one layer of an adhesive composition to a first flange of the first sheetlike element, in such a way that an end of the second flange of the second sheetlike element is indented by a distance relative to an end of the first flange of the first sheetlike element. The systems and methods bead the first flange of the first sheetlike element around the second flange of the second sheetlike element and, after the beading, an adhesive-composition part is placed around an edge of the first flange of the first sheetlike element and bonded to a second surface of the first flange of the first sheetlike element.

A method of manufacturing a vehicle body is disclosed. A frame member is formed to have a tubular shape in an open cross-sectional structure in which one side surface thereof is opened and a fastening portion is formed in a shape to close an opening portion at an end of the frame member. The fastening portion and the frame member are formed so that the fastening member closes the opening portion at the end of the frame member and the fastening portion is configured to be fastened to another frame member by a fastener in a surface-contact state.

A fuel cell vehicle includes a vehicle body, a tank mounted on the vehicle body, a fuel cell unit configured to generate electricity by using gas supplied from the tank, and a first band configured to fix the tank to the vehicle body. The tank includes a valve-side end including a cap to which an automatic valve is attached, a base-side end opposite to the valve-side end, and a cylindrical tank side surface extending between the valve-side end and the base-side end. The first band extends in a circumferential direction along the tank side surface, and is located within a range of a first predetermined distance ±15 mm from the base-side end or within a range of a second predetermined distance ±15 mm from the valve-side end.
