Abstract: PURPOSE: A high-sensitivity and high-selectivity mercury ion sensing technique is provided to sense the mercury ion based on the spontaneous and selective oxidation-reduction reaction between the mercury ion and the carbon nanotube. CONSTITUTION: A mercury ion sensor comprises a substrate, a source electrode(13), a drain electrode(14), and a carbon nanotube transistor. The carbon nanotube is connected between the source electrode and the drain electrode. The carbon nanotube makes the oxidation-reduction reaction with the mercury ion. The carbon nanotube is the single-walled carbon nanotube. The mercury ion sensor detects the mercury ion by measuring the conductance change of the carbon nanotube by the oxidation-reduction reaction of the carbon nanotube and the mercury ion.

Abstract: PURPOSE: A humidifier of a polymer electrolyte fuel cell, and a system thereof are provided to supply water generated in the inside of the fuel cell into air and fuel again, and to operate the discharge of the water and the humidification of the air and the fuel at the same time. CONSTITUTION: A humidifier of a polymer electrolyte fuel cell(10) comprises the following: a pulsation unit(110) applying a pulse flow to fuel inserted to the fuel cell; and a humidifying unit(120) including a porous permeable membrane to pass through the fuel inserted into the fuel cell while being installed in between the fuel cell and the pulsation unit. The humidifying unit absorbs water discharged from the fuel cell by the pulse flow, passes through the fuel, and supplies the absorbed water to the fuel.
