Title: 전해질의 유동에 의한 전위생성 전해조 및 그 스택

Filed: 2020-12-07
Abstract: 본 발명은 전해질 수용액을 횡단 자기장 아래에서 고속 유동시키면, 자속이 시변자속이 되어 전해질 유체에 운동 기전력이 생성되는 원리를 수소생산을 위한 수전해 장치로 구현한 것이다. 전해질이 고속 유동하는 특징적인 장치구성을 통해 종래 수전해 방식에서 에너지 효율을 가장 크게 저해하는 요소인 수송저항을 다음과 같이 획기적으로 낮춘 전해조를 제안한다.  

고속으로 유동하는 이온이 전극과 접촉하여 반응을 하므로, 약 10 -7 m/sec(10 -4 mm/sec)에 불과한 미시적인 이온 이동도에 의존하는 종래 수전해에 비해 이온의 수송이 획기적으로 개선되어 이온저항 및 전해질 확산저항의 여지가 없다.  
  
또한, 산화 환원 반응으로 각 유로에서 생성된 기체는 생성되자마자 전해질의 유동의 속도와 압력에 의해 배출되기 때문에, 기포저항은 발생하지 않는다.  
  
한편, 분리막 없이 양극유로에서 생성된 양이온(H 3 O + , H + )은 음극유로로 음극유로에서 생성된 음이온(OH - )은 양극유로로 재순환된다. 따라서 종래의 분리막저항은 없으며 각 전극 주변의 이온 및 pH가 반응에 유리하게 유지되어 추가 과전압 발생을 방지할 수 있다.
