Abstract: Disclosed is a metal-air fuel cell based on a solid oxide electrolyte employing metal nanoparticles as fuel. The metal-air fuel cell includes an anode, a cathode, a solid oxide electrolyte and a metal fuel, wherein the metal fuel comprises metal nanoparticles having an average particle diameter ranging from 1 nm to 100 nm. The metal nanoparticles have a low melting point and provide high reactivity. Thus, the metal-air fuel cell forms a metal molten phase at a relatively low temperature thereby improving contactability and has improved reactivity to promote oxidation, thereby enabling highly efficient power generation.

Abstract: Disclosed herein is a liquid drum type fuel cell-metal recovery apparatus, which can produce power through electrochemical oxidation of coal by continuously receiving coal/metal oxide mixed particles.

Abstract: Disclosed is a fluidized bed atomic layer deposition device for manufacturing nanocoating particles. A fluidized bed atomic layer deposition device according to an embodiment of the present invention comprises: a fluidized bed reactor, into which particles to be coated are injected; a reaction material supply unit for supplying reaction gases for coating the particles to be coated into the fluidized bed reactor; and a vibration pump coupled to the fluidized bed reactor such that the reaction gases can move therethrough, the vibration pump giving the reaction gasses regular vibration and thereby forming a turbulence inside the fluidized bed reactor.
