Title: Precursor organic solutions of tetravalent metal phosphates and pyrophosphates and their use for electrode modification and for the preparation of composite membrane for fuel cells working at temperatures >90.degree.c and/or at low relative humidity
Inventor: ALBERTI GIULIO
IPC: H01M8/00
Filed: 2004-08-18
Granted: 2012-10-09
Abstract: The invention is based on the preparation of precursor organic solutions of tetravalent metal phosphates and pyrophosphates with composition M(IV)(O3P-OH)2, M(IV)[O2P(OH)2]2[O2PO(OH)] and M(IV)P2O7 (M= Zr, Hf, Ti). An important property of these solutions is that the said compounds are formed when the solvent is evaporated. This peculiarity allows an easy insertion of the compounds inside the pores of porous membranes, in polymeric membranes and in the electrodic interfaces of fuel cells. The acid properties of their surfaces, the high thermal stability and the insolubility in water make these particles extremely of interest for improving the efficiency of PEMFCs in the temperature range 90-130~C. The peculiar characteristics of non-water assisted proton conductivity of M(IV)[O2P(OH)2]2[O2PO(OH)] compounds open new prospects for their application in PEMFCs at low relative humidity.

Abstract: An adaptive gate drive for an inverter includes control circuitry having a Field Programmable Gate Array (FPGA) and includes power circuitry having a plurality of FETs for operating a switching device, such as a Trench Gate Insulated Gate Bipolar Transistor (IGBT device). The control circuitry provides switching signals for operating the switching device. In addition, the control circuitry receives signals of output current of the IGBT device, temperature of the IGBT device, and DC link voltage. The FPGA has a plurality of operating points stored therein. Each operating point has corresponding parameters for a control signal that is used to control the turn-on or turn-off behavior of the IGBT device. During operation, the control circuitry compares the measured current, voltage and temperature operating points stored in the FPGA and sends the corresponding parameters to the gate drive circuit.  The gate drive modifies the signal on the gate of the IGBT accordingly and thereby optimizes the turn-on and/or turn-off behavior of the device based on actual operating conditions.

Abstract: The filter contaminant loading capacity of a depth granular media filter is increased by imposing a so-called "back-slip" on the filter bed. At intervals between normal backwashing, a volume of liquid is passed upwardly through the media bed under flow conditions selected to displace at least some of the contaminants upwardly in the bed while essentially removing none of the contaminants from the filter vessel. Preferably, the filter bed comprises at least two media types of different but uniform particle sizes and densities, the media types each forming a distinct layer in which the effective particle size of the media in each successive layer decreases in a downward direction in the vessel.
