초록

본 논문에서는 초음파나 교반 없이 전해질막과 확산층을 분리하기위한 새로운 방법에 대해 연구하였다. 증류수, 부탄올, 계면활성제를 이용하여 연료전지 막전극접합체의 전해질막과 확산층을 침지법으로 촉매입자의 분산 없이 분리하였다. 또한 분리된 확산층의 촉매와 연료전지 Pt/C 촉매를 왕수에서 $80{\sim}85^{\circ}C$로 가열하여 촉매입자를 녹여 침전제를 첨가하였다. 이후 소성하여 백긍 금속을 회수하였고 이는 새로운 연료전지용 전극촉매를 만드는데 사용될 것이다.

Present paper reports a new method to separate the electrolyte membranes and carbon paper without using ultrasonic waves and stirring. In this method, these were separated from fuel cell membrane-electrode assembly(MEA) using the distilled water, butanol and surfactant by dipping method without the dispersion of catalyst particles. Separated carbon paper catalysts and fuel cell Pt/C catalysts were heated in aqua regia at $80{\sim}85^{\circ}C$ and added to precipitant. After calcination, Pt metal was recovered which might be used in fabricating new fuel cells.
