Abstract

We report the ultra-low energy electron beam (EB) irradiation system as a key tool in order to develop new electrolyte membranes for direct methanol fuel cells (DMFC) applying a barrier strategy. The system called Min-EB consists of EB tube, EB housing and high voltage power supply. Electron beam created from hot tungsten filament by thermionic emission mechanism in the high vacuum tube. EB is passed through the silicon base membrane and emitted into EB irradiation region such as reactor chamber or atmospheric space. Low energy electron beam penetrates only the top surface of electrolyte membranes and improves the characteristics of the membranes
