고분자 전해질 연료전지에서 $TiO_2$-Nafion 혼합막에 관한 연구

A Study on $TiO_2$/Nafion composite membrane in PEMFC

Proton exchange memb rane fuel cell has been considered one of the next generation power source for electric vehicles due to high power density and low emissions. $TiO_2$/Nafion composite was prepared by the in-situ sol-gel method. The electrochemical characteristics of the $TiO_2$-Nafion composite membrane were evaluated by current-voltage and impedance of the membrane eletrode assembly in a single Proton exchange membrane fuel cell (PEMFC).
