A hydrogen compression system includes an inner container made of a non-magnetic element and having a hydrogen inlet/outlet portion through which hydrogen flows in or out of the inner container, a metal hydride material accommodated in the inner container, an outer container configured to surround the inner container and having an inlet/outlet port through which hydrogen flows in or out of the outer container, and an induction heating unit disposed between the inner container and the outer container and configured to heat the metal hydride material by induction heating, thereby obtaining an advantageous effect of simplifying a structure and process for heating the metal hydride material and quickly heating the metal hydride material to an accurate temperature.

Hydrogen compression system

A storage system for storing solid hydrogen includes: a plurality of storages including two or more types of solid hydrogen storage materials having different magnetic intensities; a storage container configured to accommodate the storages; and a coil disposed inside the storage container and configured to apply a variable magnetic field to the storages accommodated in the storage container.

Solid hydrogen storage system

A system for storing solid state hydrogen includes: a solid state hydrogen storage pellet including a magnetic material and storing solid state hydrogen therein; an inner container surrounding the solid state hydrogen storage pellet; and a coil surrounding the inner container, wherein when current is supplied to the coil, the current reacts with the magnetic material included in the solid state hydrogen storage pellet to form an induction magnetic field, thereby heating the solid state hydrogen storage pellet.

System for storing solid state hydrogen

A method for transmitting data of a wireless keyboard device having a track-ball, which transmits track-ball data and keyboard data more effectively, and thereby simplifies the process and reduces the current consumption of the keyboard device. The data transmission method transmits a leader signal composed of five chips including three consecutive low signals followed by a high signal and a low signal, thereafter transmits data that contains track-ball data and keyboard scan data recorded in the same data format, and, instead of check-sum code, allocates the complementary value of the code value of the third byte (Byte ) into the fourth byte (Byte ) and transmits it so that the transmission error can be checked by simply comparing the third byte and the fourth byte.
