Abstract: The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.

Abstract: An apparatus and a method of firing a unit cell for a solid oxide fuel cell performs pre-sintering and main sintering using a single apparatus by adjusting a height of a setter to apply pressure. The pressure prevents warping.

Abstract: A battery management system includes a sensing unit to generate a sensing signal indicating a battery voltage and a battery current of a battery, a memory unit to store a charge map recording a correlation between first to nth reference state of charge (SOC) ranges, first to nth reference currents and first to nth reference voltages for multi-stage constant-current charging, and a control unit to change to constant voltage charging using a kth reference voltage corresponding to a kth reference SOC range in response to the battery voltage having reached the kth reference voltage during constant current charging using a kth reference current corresponding to the kth reference SOC range to which an SOC of the battery belongs. The control unit updates the kth reference current of the charge map based on a time-series of the battery current in a charging period of the constant voltage charging.

Abstract: The present invention relates to a firing cartridge, and more particularly, to a firing cartridge in which multiple slit grooves are formed in lateral portions positioned between an upper end portion and a lower end portion, and solid fuel cell electrodes are inserted into the slit grooves, such that the number of cells, which may be fired at the same time, is increased, and thus productivity of a solid fuel cell may be improved.
