Abstract: A fuel cell, of proton-exchange-membrane type, includes, stacked in the following order: a first terminal, an end anode plate, a plurality of membrane plates having a bipolar plate between every two membrane plates, an end cathode plate and a second terminal Each bipolar plate includes, preassembled in the following order: a medial cathode plate and a medial anode plate, each medial anode, end anode, medial cathode and end cathode plate comprising at least one duct for distributing a reactant. The anode end plate is produced by a bipolar plate of the same orientation, and an anode capable of obturating all of the ducts of the medial cathode plate of this bipolar plate. The cathode end plate is produced by a bipolar plate of the same orientation, and a cathode capable of obturating all of the ducts of the medial anode plate of this bipolar plate.

Abstract: A method for controlling humidity in a fuel cell, wherein hydrogen is fed at a nominal pressure to the inlet of the cell, characterized in that at predetermined periodicity the following steps are repeated: instruction is given to open a hydrogen purge valve arranged on the outlet of the anode circuit; the pressure of hydrogen is measured at the inlet to the anode circuit of the cell, and the measured value is compared with a threshold pressure value; the purge valve is closed when the measured pressure is equal to or lower than the predetermined threshold pressure value; the opening time of the purge valve is measured; and the humidity level prevailing at the cathode of the cell is inferred therefrom.

Abstract: A method for producing a membrane electrode assembly for a fuel cell comprising a proton exchange polymer membrane, catalyst layers, and first and second gas diffusion layers, the method comprising the following steps: a) forming a catalytic layer coating on a first surface of the membrane, the opposite surface being supported by a spacer; b) forming a catalytic layer coating on a first surface of the first gas diffusion layer; c) bringing the first surface of the first gas diffusion layer into contact with the surface opposite to the said first surface of the membrane, after removing the spacer, and bringing the first surface of the membrane into contact with a surface of the second gas diffusion layer.

Abstract: An apparatus and method for simultaneously removing materials from fluids without the need for added chemicals, and without the formation of toxic byproducts, by high-density plasma reaction chemistry is described. Applications to removal of contaminants, such as pesticides, organics, PPCPs, and pathogens, as examples, from water are discussed. Changes in the quality of the raw water are not expected to adversely affect the decontamination process.

Each candidate list identifies one or more available employee candidates meeting the staffing requirements from each of a plurality of staffing agencies.

Abstract: A method of assembling a knowledge database containing question and answer pairs, the method comprising the steps of: extracting questions from a multiplicity of electronic communications; enabling the sender of the communication to examine and select or deselect the extracted question(s); classifying each question based upon the content of the question and identifying keywords in each question; entering the questions into the database together with their respective classifications and keywords; and entering into the database answers corresponding to the entered questions; wherein an answer to a question may be found by classifying the question and identifying keywords therein, identifying questions contained in the database which have the same or a similar classification and which contain some or all of the same keywords, and identifying the corresponding answers

Abstract: A vaginal tampon contains living lactic acid bacteria (lacto-bacteria) and/or auxiliary substances for treating or regenerating the vaginal flora. The lacto-bacteria and auxiliary substances are enclosed in an air- and water-tight manner between thin layers, which are at least partially dissolved only when the tampon is used. The vaginal tampon releases the lacto-bacteria and/or auxiliary substances.

Abstract: Molecular Complexes, comprising of S-(+)-adenosylmethionine and 3'-azido-2',3'-dideoxy nucleosides are prepared, and shown to have synergistic inhibitory effects on the replication of human-immunodeficiency virus 1 & 2 in vitro and in vivo, particularly on the reverse transcriptase, and having a high therapeutic index.

Abstract: An integrated circuit formed on a semiconductor substrate has a contact pad for communicating signals between an external device and an internal signal line. The pad is protected by an SCR that conducts electrostatic discharge pulses from the pad directly to a current sink. The SCR includes a subregion underneath a field oxide that has a field inplant that increases the dopant concentration. The field implant lowers the SCR trigger voltage, so that SCR triggers before an ESD pulse can cause latch-up or damage in other devices in the integrated circuit.

Abstract: The invention concerns integrated circuits in which a MACRO is embedded in a standard cell array. One level of metal is devoted exclusively to non-local interconnect, and a layer of polysilicon is devoted to local interconnect, thereby saving significant space.
