PURPOSE: A fuel cell adapter system for combustion tools is provided to protect a fuel cell from dirt and other debris while in use and protect a fuel cell stem during transportation, thus eliminating the need for a protective cap or blister pack. CONSTITUTION: A fuel cell adapter system for a combustion tool includes a housing enclosing a fuel metering valve(13). A fuel cell(14) is provided with an adapter(16) having a generally cylindrical nozzle(20) and a base(22) configured for engagement upon the fuel cell. The nozzle has a free end and defines a passageway. A frangible membrane is provided for blocking the passageway. The adapter also has a gripping formation(40) that is configured for engagement with a latch(60), so that the adapter is accommodated in the housing in fluid communication with the fuel metering valve. The latch is disposed in the housing for releasably securing the adapter in fluid communication with the fuel metering valve. The latch includes a latch body(62) having at least one locking tang(64) movable between a closed position and an open position, and a release member for moving the locking tang to release the engagement with the adapter and permitting withdrawal of the fuel cell from the tool.
