FUEL CARTRIDGE FOR FUEL CELL

摘要

A fuel cartridge for a fuel cell with which the structure where an open part of a flexible container where a connecting fixture is mounted and a cover member are joined together can be simplified in order to improve volume efficiency, and the operation of screwing on a stationary tube member can be performed reliably. An open part (14) of a container (10) protrudes from an open part at the front end of a cover, and a retaining cap (33) is screwed onto the outer circumference of the protruding part (14a) of the open part of the container that protrudes from the open part at the front end of the cover to secure a coupler plug (30P). A rotation prevention mechanism (2) that mutually engages in the tightening direction of the retaining cap (33) when the retaining cap (33) is screwed in and that prevents the retaining cap (33) and the container (10) from rotating together is provided between the facing surfaces of the outer circumference of the open part (14) of the container and the inner circumference of the open part (14a) at the front end of the cap.
