Moreover, it provides the pressure-sensitive adhesive composition which can cover step differences and defects and can minimize air bubbles or liftings between laminated layers while satisfying fundamentally required physical properties such as durability and pressure-sensitive adhesive. Especially, it provides the pressure-sensitive adhesive composition capable of minimizing air bubbles or liftings between laminated layers while satisfying fundamentally required physical properties such as durability and pressure-sensitive adhesive even when left at high temperature for a long time. It also provides an optical pressure-sensitive adhesive product which can cover defects located between laminated layers for a display module or a transparent electrode product.

Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: Disclosed is a multi-band antenna unit of a mobile terminal that includes an antenna, switch, sensor, first matching circuit, second matching circuit, diplexer, first signal processing unit, and second signal processing unit. The antenna is movably installed between first and second contacts, and transmits and receives first and second signals of different frequency bands. The switch connects the first contact to the first matching circuit or the second contact through the second matching circuit. The sensor detects an antenna position, and allowing selective connection of first or second matching circuits. Transmission and reception of multiple signals of various frequency bands is enabled using a single antenna unit, reducing the number of components, cost, and size of a mobile terminal. Additionally, performance of an antenna is improved by connecting to a proper matching circuit according to the position of the antenna.
