마이크로웨이브를 이용한 고분자 전해질 연료전지용 복합 탄소촉매 지지체 (ACF/Graphene)의 합성과 전기화학적 거동 = Synthesisand Electrochemical Behaviors of Hybrid Carbon ACF/Graphene) as Supports by Microwaves-irradiation Method for Polymer Exchange Membrane Fuel Cells (PEMFC)

다국어 초록 (Multilingual Abstract)

Carbon materials are mainly used as catalyst supports for polymer exchange membrane fuel cell(PEMFC). Catalyst supports are required specific characteristics of the carbon materials, such as large surface area and high electrical conductivity. Attempted were to improve electrical conductivity and to maintain high surface area of carbon materials using a microwave treatment. Microwave treatment, as a relatively new technique, takes short reaction time and reduce the consumption of the gases used for carbon treatment compared to a traditional heat treatment. Hybrid carbon (ACF/Graphene) as catalyst supports by microwave-irradiation method for PEMFC increase the cell performance because of increased electrical conductivity resulting in triple-phase contact and reduced the interfacial resistance. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-Ray Diffraction (XRD) were employed to analyze carbon materials. The performance of microwave-treated carbon materials was evaluated by measuring current-voltage (I-V) characteristics and electrode impedance.
