국립부경대 나노융합공학전공 서민호 교수와 한국재료연구원 최승목 박사, 광주과학기술원(GIST) 엄광석 교수 연구팀이 세계 최초로 개발한 신 탄소물질을 전극의 제조 공정에 첨가제로 활용해 상용 수준의 고분자전해질연료전지시스템의 내구성을 획기적으로 높이는 데 성공했다.
친환경 고효율 전지로 주목받는 고분자전해질연료전지는 수소를 연료로 수소산화반응을 통해 전기를 생산하고, 반응 결과물로 물만 배출하는 발전 장치다. 하지만 기존 고분자전해질연료전지 시스템에서는 시동 온/오프 과정에서 1.4V 이상의 높은 전압이 발생해 촉매층의 탄소 부식이 가속화되고, 이에 따라 촉매층 붕괴 및 산소환원반응 시 생성되는 물이 전극 내부에 넘치는 현상(water flooding)으로 내구성이 급격히 감소하는 문제가 있었다.
서민호 교수 연구팀은 고탄소 내부식성을 가진 신 탄소물질을 전극 내 첨가제로 활용, 탄소 부식으로 인한 연료전지 내구성 저하를 효과적으로 개선했다. 이번 연구에서 활용된 플루오린 도핑 그래핀나노리본과 탄소나노튜브 복합체(F-GNR@CNT)는 기존 그래핀나노리본 산화물의 탄소 부식 취약성을 극복하기 위해 개발됐다.
이번 연구성과는 국립부경대 신진연구자 도전연구, 한국에너지기술평가원, 한국산업기술기획평가원 및 한국재료연구원의 기본사업의 지원을 받아 수행됐다.

There were perfect counters, dodging, grappling, and air juggling. It was a BnS NEO Divine Gems game I would become obsessed with, waiting for each new trailer to appear in a grainy 720p. But excitement came and went, as Blade and Soul eventually found a Western release in 2016, four years after its debut in Korea. It didn’t arrive with a bang, but instead a whimper. And while NCSOFT pushed for an active PvP scene, it didn’t come to fruition.
Plagued with bots, gold-sellers, and an obvious favoritism towards specific races and classes, Blade and Soul clung on. However, in January 2025, NC America announced it was bringing Blade and Soul Neo, a revamp of the MMORPG made in Unreal Engine 4, to the West. And given its status as a “modern reinterpretation” of this once promising MMORPG, it’s more of a remaster, carrying over almost all of the issues from its original debut in the West.
Blade and Soul Neo is exactly what it claims to be. Remade in Unreal Engine 4, it’s more or less an exact replica of the game as it was released in 2016. There are a few things here and there that have changed such as a new user interface that is a bit easier to manage, but still has that cheap, simplistic shine of the modern Korean MMORPG, and a few adjustments to how players can acquire specific items.
The story is the same; you are the promising young student of a martial arts master that is betrayed by a former pupil, Jinsoyun. It is up to you to seek revenge against this foe and the various factions that have allied with her in some shape or form. While the premise is more or less stock and standard for Chinese wuxia stories, its flair for the dramatics keep it interesting and character moments engaging.
However, like most NCSOFT games of its era, the translation and voice acting are less than stellar. Blade and Soul Neo keeps the original voice acting and script, so nothing has changed here. Which is a shame, because the narrative of cheap Blade and Soul NEO Classic Divine Gems is at least moderately compelling and unlike whatever else is on the market, so it could keep players interested — as I played the Japanese version of the game long enough to compare notes, back in the day. It feels like a huge missed opportunity with the Western market’s interest in traditional Chinese storytelling.
