Abstract: Disclosed are a separator for a fuel cell that improves power characteristics of the fuel cell, and a fuel cell including the same. The separator includes a plurality of current-carrying units, and an insulating unit interposed between the current-carrying units, wherein each current-carrying unit includes a first polymer matrix in which carbon-based particles are dispersed, and the insulating unit includes a second polymer matrix in which insulating inorganic particles are dispersed. The separator for fuel cells includes an insulating unit that exhibits low gas permeability and superior electrical insulation property, and the current-carrying unit that exhibits superior strength characteristics and conductivity, thus increasing voltage generated per one cell and considerably increasing a power generated per a constant area, when applied to the fuel cells.

Abstract: The present disclosure provides a non-pneumatic tire. The non-pneumatic tire includes an outer cylindrical section having a tire tread; an inner cylindrical section connected to an axle of a vehicle; and a noise and vibration prevention spoke unit connecting the outer cylindrical section to the inner cylindrical section. The spoke unit is continuously supported by a road surface during vehicle driving, thereby reducing noise and vibration. In the non-pneumatic tire, the spoke blades are arranged at an angle, so that the spoke unit is continuously supported by a road surface during vehicle driving, thereby enabling reduction of noise and vibration while improving ride comfort. In addition, the non-pneumatic tire allows a designer to set lateral forces, as needed, as opposed to a conventional non-pneumatic tire, thereby enabling control of a leaning phenomenon caused by road structure.
