FUEL CELL SYSTEMS AND RELATED METHODS

摘要

A fuel cell system having a fuel cell generator and a fuel cartridge that is removably attachable to the fuel cell generator is disclosed. The fuel cartridge includes a housing having a port, a normally closed valve disposed in the housing that gates fuel emerging from the port, the valve having a poppet that modulates opening of the valve, the poppet having a control surface. The fuel cell generator has a moveable pintle coupled to the poppet, and the moveable pintle is operative over a range of motion which causes the poppet to move between a closed state and at least one open state.
