摘要： The present invention concerns a fuel supply for a fuel cell. The fuel supply includes a fuel storage area configured to hold a fuel solution, a fuel solution outlet configured to pass the fuel solution from the fuel storage area, a waste storage area, a waste inlet configured to pass waste into the waste storage area, and a movable barrier separating the fuel storage area and the waste storage area. The movable barrier is configured to move as fuel solution is passed from the fuel storage area and waste solution is passed into the waste storage area to simultaneously decrease the volume of the fuel storage area and increase the volume of the waste storage area.

摘要： Hydrogen generation system. A source of sodium borohydride is carried on a flexible substrate that moves from a feed roll to a takeup roll. A reaction among sodium borohydride, a catalyst and water evolves hydrogen and forms a by-product that is removed from the reaction area.

摘要： A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir of a fuel cell. The fuel concentration is determined using a dye mixture responsive to fuel concentration within a fuel solution. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the dye changes color. The resulting color changes occur within the anode reservoir of the fuel cell, or within a dye chamber in fluid contact with the anode reservoir, and are made visible by a window. A color strip and fuel scale may be included to facilitate fuel concentration determination based on the color of the fuel solution. Additionally, a valve responsive to dye color may act to control fuel delivery.

摘要： A means for determining the concentration of a hydrogen-rich fuel in a fuel solution within the anode reservoir of a fuel cell. The fuel concentration is determined using a float responsive to fuel solution density. As fuel is consumed, the fuel concentration decreases. As the fuel concentration decreases, the density of the fuel solution increases, causing the float to rise. A window may be included in the anode reservoir or in an attached float chamber to facilitate inspection of the position of the float. A fuel scale may be included to facilitate fuel concentration determination based on the position of the float within the fuel solution. Additionally, a valve responsive to float position may act to control fuel delivery.
