초록

In order to develop key technologies for a kW class for polymer electrolyte fuel cell (PEFC), various membranes (Nafion(112, 115, 117), Dow, Flemion, Gore, and Hanwha), and electrocatalysts (Pt/C, PtNi/C PtNiCo/C and PtRu/C) were used in the fabrication of the MEAs by using transfer printing technique. The effects of the thickness of Nafion membranes, electrocatalysts and the operating conditions (e.g. temperature, reactant gas pressure, and composition) on the performance of the MEA were investigated in the PEFC single cell($O_2/H_2$, and Air/$H_2$ cell). The performances of the MEAs for $O_2/H_2$ and Air/$H_2$ cells has been evaluated.
