EFFECT OF MEA HOT-PRESSING ON THE PERFORMANCE OF DIRECT METHAN OL FUEL CELLS

Donghui Shen, Hailun Chen, Aihua Tian

ABSTRACT:MEA based on Nafion 115 has been prepared with GDL-based method for direct methanol fuel cell applications. The results of unit cell tests show that different temperature and pressure of hot-pressing during MEA preparation presents different polarization curve. Optimization of temperature and pressure during hot-pressing can effectively improve the performance of direct methanol fuel cells.
