2 Dept. of Biomed. Eng.BME302: Medical InstrumentationKyung Hee Univ. 2 박준환 1. Electrode-Electrolyte Interface 1) Basics( 기본개념 ) + - V Anode Cathode 이온 전류 (Ionic current) 전자 전류 (electronic current)

3 Dept. of Biomed. Eng.BME302: Medical InstrumentationKyung Hee Univ. 3 박준환 1. Electrode-Electrolyte Interface 2) Experiment( 그림은 위와 동일 ) (Pt-Pt) - 두 전극 모두에서 기포발생 - 전극은 변화없음 (C-C) - 두 전극 모두에서 기포발 생 - 양극의 Carbon 부식 (Ag/AgCl-Ag/AgCl) - 기포없음 ( 적은전류 ) - 양극 색 변화 X : 암갈색 - 음극 : 암갈색 → 은색
