This disclosure is drawn to systems, devices, apparatuses, and/or methods, related to fuel cell cartridges. Specifically, the disclosed systems, devices, apparatuses, and/or methods relate to compact fuel cell cartridges for producing hydrogen gas for use by fuel cells. Some example fuel cell cartridges may include a reactor module for storing a reactant, a water module for storing water, and an interface coupling the reactor module and the water module. The interface may permit the water to flow from the water module to the reactor module such that the water mixes with the reactant in the reactor module to form a gas (e.g., hydrogen gas) that may exit through a gas outlet.

Fuel cell cartridge

There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a portable fuel cell power and management system (for example, hydrogen and/or methanol based systems), components and/or elements thereof, as well as techniques for controlling and/or operating such systems. The fuel cell power management system (and method of controlling and/or operating same) actively monitors, manages and/or controls one or more operating parameter(s) of the fuel cell system. For example, the system monitors, manages and/or controls the consumption and/or the rate of consumption of fuel by the system, and in response thereto, may provide and/or alert the user to amount of fuel remaining, consumed, the rate of consumption and/or the time (or estimation thereof remaining until all of the fuel is spent. In this way, the user may schedule or plan accordingly.

System for a fuel cell power and management system

Power unit for a fuel cell power and management system

A system for and method of controlling the temperature of a flat workpiece such as a semiconductor wafer are disclosed. The workpiece is mounted on a workpiece chuck which is mounted over a base between the chuck and a host machine such as a wafer prober used to test integrated circuits on a wafer. The chuck includes an upper portion on which the workpiece is mounted. The temperature of the upper portion of the chuck is controlled to control the temperature of the workpiece. The temperature of the base is controlled to reduce the amount of heat flow between the chuck and the host machine. A power and control system includes a switching power supply which provides power to system components including heaters in the chuck used to heat the workpiece. A series of filters removes electrical noise generated by the switching power supply such that low-noise operation is realized.

Temperature control system for a workpiece chuck

A workpiece chuck includes an upper assembly on which can be mounted a flat workpiece such as a semiconductor wafer. A lower assembly is mountable to a base that supports the chuck. A non-constraining attachment means such as vacuum, springs or resilient washers applied to the chuck holds the upper assembly to the lower assembly, the lower assembly to the base and can hold the wafer to the top surface of the upper assembly. A heater and a heat sink can be included in the bottom assembly to allow for temperature cycle testing of the wafer. By holding the chuck together by non-constraining means, the chuck layers can move continuously relative to each other under expansion forces caused by temperature effects. Mechanical stresses on the chuck and resulting deformation of the chuck and workpiece over temperature are substantially eliminated.

An applicator device ( ) for coupling a snap hook ( ) to a hook connector ( ). The applicator device includes an applicator head and a receptacle ( ). The applicator head defines a snap hook receiving receptacle ( ) which is formed to position the snap hook ( ) for, and to support the snap hook ( ) during, coupling of the snap hook ( ) to the hook connector ( ) while the snap hook is engaged in the receptacle ( ). The receptacle ( ) is further formed for disengagement of the applicator head ( ) from the snap hook while the snap hook is coupled to the hook connector upon displacement of the applicator head in a direction lateral to the snap hook. A method of using the applicator device is also disclosed.

A plurality of support members including inclined surfaces provided between an upper and lower portion of the chuck maintain the top surface of the chuck and any workpiece mounted thereon at a constant height over temperature.
