Abstract: A self-contained hydrogen recharging system (5) for a fuel cell metal hydride storage canister (100). A water reservoir (10) provides water (15) to an electrolyzer (20), where the water is converted into hydrogen gas (22) and oxygen gas (24). The hydrogen gas is dried (26) and then stored in an accumulator (30). When the metal hydride storage canister is ready to be refilled, it is connected by the user to the recharging system. A heat exchanger (55) heats the fuel cell hydride storage canister prior to transfer of the stored hydrogen gas, and then cools the fuel cell hydride storage canister during transfer of the stored hydrogen gas. The hydrogen gas stored in the accumulator is rapidly transferred to the hydride storage canister by means of a pump (60) and stowed in the canister as a metal hydride.

Abstract: An adaptable mold assembly (10) consists of two mold bases (100, 102). One or both of the mold bases has at least one interchangeable portion (104, 105) removably mounted on the mold base, whose function is to actuate in a direction different from the draw direction. The interchangeable portion is typically used to facilitate the removal of the molded part from the mold, and often functions as a mold slide or pull. The ability to interchange and reconfigure the mold base reduces tooling costs and adds design flexibility to the tool. In another embodiment of the invention, the function of the interchangeable portion (106) is to provide process monitoring, process control or process optimization.

Abstract: A fuel cell power source (100) for use in electronic systems includes a fuel cell system (130) and a control means (150). The control means (150) computes net power requirements of a load device from one or more power functional information sources; and determines an operating point of the fuel cell system (130) by matching the net power requirements with the power characteristics of the fuel cell system (130).

Abstract: An apparatus and method for measuring the quantity of hydrogen in a hydrogen storage vessel (300) of a hydrogen fuel cell using the Pressure, Composition, Temperature (PCT) relationship (350) of the storage media is disclosed. The method of measuring the quantity of hydrogen (360) involves, measuring the temperature (310) of the hydrogen storage media at one or more points on the hydrogen storage vessel (300), measuring the mechanical strain (320) at one or more points on walls of the hydrogen storage vessel, computing the pressure (330) inside the vessel based on the strain measurements, referring to a look-up table (340) with PCT graph/operating curve data (350) or an equation using Van't Hoff parameters for representing the discharge PCT curve for the particular concentration at the measured pressure. The changes in temperature and pressure during hydrogen absorption-desorption which are characteristic of hydride composition is used to measure the concentration ratio of hydrogen to metal hydride as a concentration ratio of hydrogen to metal.

Abstract: An apparatus and method for temperature regulation of a fuel cell using differential heat capacity of the fuel storage media is disclosed. The method of regulating the temperature involves measuring the temperature of one or more fuel cells, comparing the temperature against target values, selecting a control method from a set of available control methods based on the result of comparison and using that control method to initiate and control a regulation cycle, and actuating a flow control means using the selected control method to alter the flow of fuel between one or more fuel storage containers, each containing fuel storage media which exhibit different enthalpies of formation and dissociation. The regulation process starts with measuring temperature (110) of a fuel cell system (100). The measured temperature is then compared (120) to a predetermined set of ideal target values designed to provide peak fuel cell performance. Following the comparison step, a control method (130) is selected from a list of available control methods. The control method has the necessary parameters and logic to define an fuel flow initiation process (140) which in turn actuates a flow control means (150). Actuation of the flow control means changes the temperature of the one or more fuel cells and alters its operating parameters (160).

Abstract: Oxides of carbon and other impurities are removed from a hydrogen fuel supply stream (12) for a fuel cell (30). A getter element (20) sufficient for chemisorbing the oxides of carbon from the hydrogen is removably connected to the fuel cell anode side. The fuel stream is passed through the getter element so as to chemisorb the oxides of carbon onto the getter, thereby providing a purified stream of hydrogen (26) to the fuel cell anode. The getter is removed from the fuel cell when the getter when spent and replaced with a fresh getter.
