• W1973432456 abstract "본 연구는 바나듐 레독스 흐름전지에서 속도 결정단계인 양극 반응(<TEX>$[VO]^{2+}/[VO_2]^+$</TEX>)을 개선하여 바나듐 반응의 속도를 증가시켜 흐름전지 성능을 향상시키고자 하는 목적으로 진행하엿다. 이를 위해, 다공성 촉매인 CMK3를 사용하여 일반적으로 사용되는 탄소 (Vulcan(XC-72)) 및 상용 Pt/C 촉매 (Johnson-Matthey사 Pt 20wt.%)와 그 성능을 비교하였다. 반응성은 순환주사전류법으로, 구조적 특성은 TEM과 BET&BJH을 이용하여 분석하였다. 또한, 완전지 실험을 통하여 전기화학적으로 나타난 결과가 어떻게 충방전에 적용되는지 확인하였다. 결과, CMK3는 Vulcan(XC-72)보다 6배 향상된 촉매 활성과 2배 이상 향상된 반응가역성이 나타남을 확인하였고, CMK3의 다공성 구조로 인해 Vulcan(XC-72) 보다 큰 표면적을 가지고 있음을 확인하였다. 아울러, CMK3는 백금 촉매가 없음에도, 상용 Pt/C 촉매의 85% 이상의 반응성과 가역성을 나타내었다. 완전지 실험에서 충방전 곡선은 CMK3를 적용한 흐름전지가 오히려 상용 Pt/C 촉매를 적용한 흐름전지보다 좋은 모습을 나타내었다. In this study, we implemented a research for improving performance of redox flow battery (RFB) via enhancing reaction rate of vanadium reaction (<TEX>$[VO]^{2+}/[VO_2]^+$</TEX>) that was a rate determining step. For doing that, porous catalyst, CMK3 was employed and its perfoamance was compared with that of Vulcan(XC-72) and commercial Pt/C (Johnson-Matthey Pt 20wt.%). Cyclic voltammetry (CV) was used for inspecting reactivity, while its structural feature was measured by TEM and BET&BJH. Also, Charge-discharge trend was evaluated by single cell tests. As result, CMK3 showed 6 times better catalytic activity and twice better reversibility than Vulcan(XC-72), while it showed larger surface area than Vulcan XR due to its porous structure. Furthermore, CMK3 indicated 85% of reactivity and reversibility of commercial Pt/C despite its Pt-less situation. In single cell tests, when RFB adopted CMK3 as catalyst for positive electrode, its charge-discharge curve result was better than that adopted commercial Pt/C." @default.
