Abstract: A polybenzimidazole based polymer in which substituted or non-substituted benzyl groups are introduced to the two nitrogen atoms of benzimidazole ring. The benzimidazole ring is not decomposed by the attack of hydroxide ions but shows excellent alkali resistance, and thus maintains high ion conductivity. The polybenzimidazole based polymers are particularly useful for not only solid alkali exchange membrane fuel cells (SAEMFC) but also various industrial fields in which polybenzimidazole based polymers are used.

Abstract: An optical element includes a multicore optical fiber, the multicore optical fiber including an inner core and at least one peripheral core arranged around the inner core and having an effective refractive index different from that of the inner core, and an optical fiber grating formed at the multicore optical fiber to cause an optical signal to be coupled between different cores among the inner core and the at least one peripheral core. The optical element allows a signal of a specific wavelength to be dropped added from an optical signal. Since the optical element may be fabricated easily, designed in a small size and mass-produced reproducibly at low costs, the optical element may be advantageously utilized for an optical communication network such as a wavelength division multiplexing network, an ultra-high speed optical communication system, an optical sensor system or the like.
