Abstract
A fluid pump and connector assembly is particularly suited for use in connecting a fuel cartridge to a fuel cell system. The assembly has a first sub-assembly comprising a fluid inlet, a fluid outlet, a flexible diaphragm in fluid communication with the inlet and outlet, and a first connector. The assembly also has a second sub-assembly comprising a second connector adapted to connect to the first connector, an actuator and a reciprocating member coupled to the actuator and contacting the diaphragm when the first and second sub-assemblies are connected, wherein a reciprocating motion of the actuator and member causes the diaphragm to reciprocate and pump fluid from the inlet to the outlet without exposing the fluid to the second sub-assembly.
