    摘要： A fuel pump driving module used for supplying fuel from a fuel tank to a fuel cell—and more particularly, a driving module for a diaphragm pump, and a fuel cell system equipped with the same—includes a pump controller for generating an ON/OFF signal and a reference pulse to a pump; and a pump driving pulse generation unit for combining the reference pulse according to a predetermined rule to determine a frequency and a duty ratio of the pump driving pulse and activating the pump driving pulse according to the ON/OFF signal to the pump. The pump driving module may be useful to commonly apply a single pump driving module to various manufacturers' fuel pumps, thereby to reduce the fabricating cost of the fuel cell system.

    摘要： A method of preparing a composite of organic and inorganic compounds includes the steps of reacting a mixed solution of a metal alkoxide and a silicon-containing compound with a catalyst to produce an alcogel of a metal oxide or a complex metal oxide. The metal alkoxide is prepared by reacting at least one metal with an alcohol and the mixed solution is prepared by mixing the metal alkoxide with the silicon-containing compound. An alcogel is produced from the reacting step and alcohol is impregnated within the inorganic oxide lattice structure of the alcogel. Furthermore, the method of preparing a composite of an organic and an inorganic compound includes the steps of centrifuging the alcogel to separate any alcohol from the alcogel to form a gel, adding an organic monomer the gel and polymerizing the organic monomer in-situ to form an organic polymer. The resulting composite has characteristics of both the parent organic and inorganic compounds.
