Method and apparatus for simultaneous controlling of fuel concentration and temperature of liquid fuel by sensor-less and temperature-control based feed-back control, liquid fuel cell apparatus using the same
A concentration of a fuel supplied to a fuel cell and a heat exchange rate of a heat exchanger are controlled simultaneously in order to maintain a temperature of fuel cell stack and a diluted fuel concentration that is supplied to the fuel cell stack in a target level. Further, by appropriately responding to an exterior temperature changes or unexpected fuel cell performance changes, it is possible to improve a system efficiency and stability of fuel cell operation and to regulate the fuel concentration quickly and accurately compared to a prior sensor-less concentration controller..

Recovery of organic acid using a complex extraction solvent
A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. An amine, c02 and a water immiscible solvent are introduced to the solution to form the insoluble carbonate salt and a complex between the acid and the amine that is soluble in both an aqueous and a solvent phase.

Method of manufacturing healthy drink using opuntia ficus-indica
Provided is a method of manufacturing healthy drink using opuntia ficus-indica, which includes the steps of: removing fruits and thorns from stems of the opuntia ficus-indica, washing the stems of the opuntia ficus-indica, and mixing and grinding 90% to 99.5% by weight of the washed stems of the opuntia ficus-indica and 0.5% to 10% by weight of roasted ginkgo nuts to thereby prepare a crude liquid of mixed materials; mixing 50% to 60% by weight of the crude liquid of mixed materials and 40% to 50% by weight of water; ripening and filtering the diluted crude liquid for 12 hours to 24 hours at temperature of 60° c. To 80° c.; mixing 0.2% to 1% by weight of at least one of pure crystalline fructose and fructooligosaccharine to 99% to 99.8% by weight of the filtered crude liquid; and sterilizing the crude liquid..
