Abstract
The invention relates to a portable cartridge that stores a fuel for use with a fuel cell system. Cartridges described herein improve mechanical interface between a cartridge and a device that couples to the cartridge. The interface may include one or more of: a sliding interface between a cartridge and device, a latching interface that holds the cartridge in one or more positions relative to the device, and/or keyed access and security features that prevent unintended access to the fuel. Multiple valves may also be included to further control access to the fuel.
