Title: Electrode catalyst for an anode pole
Inventor: POORU SUTONHARUTO
IPC: H01M4/90
Filed: 1990-09-29
Abstract: PURPOSE: To obtain an electrode catalyst for fuel cells with a superior resistance to carbon mono-oxide poisoning and a low production cost by making the catalyst have a platinum-nickel-cobalt ternary alloy supported on an inorganic carrier. CONSTITUTION: Chloroplatinic acid is dissolved into water, to which an aqueous solution of Na2 S2 O3 .5H2 O is added. Acetylene black to be a catalyst carrier is suspended into pure water to form a slurry, which is then added to the mixed solution, agitated and dried to remove water. The resulted dry powder is washed by distilled water to extract and remove by-products. This slurry is dried to obtain a carbon carrier supporting platinum. And then, an aqueous ammonium hydroxide solution is added to a mixed solution of an aqueous nickel formate solution and an aqueous cobalt acetate solution. The said carbon supported platinum catalyst is added to this aqueous solution and the resultant slurry is dried and reduced in a hydrogen stream to alloy the said platinum, nickel and cobalt.  Tetrafluoroethylene dispersion is added to this alloy catalyst and the resulted mixture is coated on a water repellent-treated carbon sheet, which is then fired to produce an electrode.

Title: Drive circuit of switched reluctance motor
Inventor: YAMADA KATASHIGE
IPC: H02P25/098
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce switching losses, electromagnetic troubles, reactive torques, and circuit losses. SOLUTION: Feedback diodes Da-Dc are connected to switching elements Ta-Tc which sequentially apply currents to each winding 2a-2c of a motor, and the other end of a resonance capacitor Cr whose one end is connected to a DC power source E is connected to the output side of Ta-Tc via diodes Dba-Dbc, and a resonance inductor Lr and a switching element Tr for resonance are connected between both terminals of Cr, and a diode Dg which bypasses the DC power source E is connected to it. Just before turning off the Ta-Tc, Tr is turned on, and Cr is charged Vcr into reverse polarity with the resonance of Cr, and currents are applied to Da-Dc by Vcr, and Ta-Tc are turned off in zero-volt condition, thus switching losses and electromagnetic troubles are removed.  A current iLa of 2a flowing at this time flows with the circuit of Dg, Cr, and Dba, and since a resonance circuit is made of La and Cr, ILa decreases sharply, and reactive torque decreases. Since current is not applied to Lr, excluding the time of resonance with Cr, loss is small.
