NOVELTY - Apparatus to secure a cartridge (402) comprises a cartridge having a cartridge interface (404); an interface fluid outlet port disposed on the cartridge, the outlet port in fluid communication with an interior of cartridge, and configured to mate with a receiver fluid inlet port of a cartridge receiver; an orientation angle measured between the outlet port and plane orthogonal (412) to insertion path of cartridge such that the outlet port and the insertion path are nonparallel; and a biasing member configured to apply a force that presses the outlet port against the inlet port.    USE - For securing a cartridge (claimed) in fuel cartridge.    ADVANTAGE - The apparatus is safe and efficient; is durable, intuitive and use fewer components than other alternatives; and prevents the cover from fully closing when the fuel cartridge is improperly inserted in the cartridge receiver.    DETAILED DESCRIPTION - Apparatus to secure a cartridge (402) comprises a cartridge having a cartridge interface (404); an interface fluid outlet port disposed on the cartridge, the outlet port in fluid communication with an interior of cartridge, and configured to mate with a receiver fluid inlet port of a cartridge receiver; an orientation angle measured between the outlet port and plane orthogonal (412) to insertion path of cartridge such that the outlet port and the insertion path are nonparallel; and a biasing member configured to apply a force that presses the outlet port against the inlet port. The apparatus further comprises the interface fluid inlet port disposed on the cartridge interface, the inlet port in fluid communication with the interior of the cartridge, and configured to mate with a receiver fluid outlet port of the cartridge receiver; at least one alignment features configured to ensure that the insertion path of the cartridge and an alignment of the cartridge are proper; a cartridge receiver; a receiver gas port disposed on the cartridge receiver; a biasing member removably securing the cartridge to the cartridge receiver; a cartridge cooling module configured to conduct heat away from the cartridge. An INDEPENDENT CLAIM is included for system to secure a fuel cartridge that generates hydrogen comprising a fuel cartridge configured to contain a hydrogen generating reaction; an interface gas outlet port; a cartridge receiver configured to receive the cartridge interface of the fuel cartridge; a receiver gas port disposed on the cartridge receiver; and a biasing member.
