Abstract: FILTER PRESS ELECTROLYZER                       Abstract The present invention relates to a filter press electrolyzer of the type having front and rear bulkheads.  The electrolyzer comprises an electrolytic cell between the bulkheads.  The cell comprises a pair of planar electrode assemblies, typically including a center compartment assembly therebetween, all in a stacked relationship.  Separators are clamped between the electrode and center compartment assemblies.  Each electrode assembly comprises an annular frame defining an electrolyte chamber, a planar electrode member having an electrode active area within said chamber, and a current distributing bus on the side of said electrode member which is opposite the side facing said separator. The current distributing bus has a planar surface area which is substantially co-extensive with the electrode active area.  Each of said electrode assemblies comprises a plurality of spaced-apart separator strips affixed to the electrode member on the side opposite the current distributing bus.  The separator strips separate the electrode member from the separator.  The bulkheads include means for compression of the electrode assemblies one against the other.  The separator strips of the electrode assemblies are aligned so that the separator strips transmit the compression forces within the electrolyzer from one electrode assembly to the other.

Filed: 1993-10-28
Abstract: A solid polymer fuel cell electric power generation system (10) removes a substantial portion of water accumulated at the cathode in the outlet fuel stream (18) of the anode. The system permits the operation of a hydrogen/oxygen fuel cell (1) in a deadended mode where substantially pure oxygen is employed as the oxidant supply (54) or using low oxygen stoichiometry where a dilute oxidant source, such as oxygen-containing air, is employed as the oxidant supply.

Title: Low voltage sensing circuits for battery powered devices having a micro-processor
Inventor: MARTINSON GLEN D
IPC: G01R31/36
Filed: 1995-08-02
Abstract: A low voltage sensing circuit for a battery powered, micro-processor based circuit is provided. A standard voltage regulator has input voltage from a battery, and output voltage which is fed to a system requiring the same, which includes a micro-processor. A voltage divider is connected through a capacitor to an output port of the micro-processor; and the common point of the voltage divider is connected to the base or emitter of a transistor. Periodically, there is an output pulse from the output port of themicro-processor, which pulse has a predetermined length. During the output pulse from the micro-processor, the transistor may become conductive while the capacitor is recharging. Depending of the configuration, the fact that the transistor is conductive is indicative that the input voltage is either below orabove a predetermined value. The width of the pulse that is created across a resistor connected to the collector of the transistor and also to an input port of the micro-processor, is indicative of how much below or above the predetermined value the input voltage from the battery has deviated. The predetermined input voltage is established by setting the values of the resistors in the series connected voltage divider.
