Examination of Orthogonal Channel Extrusion Method

— A New Method of Extrusion of Fuel Cell Separator
Using Orthogonal Channel I —

Abstract

In recent years, the fuel cells have attracted attention in relation to the environmental problems of the earth. And studies on the improvement of the productivity of the fuel cell are required. The separator in a fuel cell is important. The manufacture of separators usually involves injection molding or compression forming. However, in terms of productivity, the manufacture of separators by extrusion has advantages. Thus, the aim of this research is the development of a new method of extrusion of a fuel cell separator using an orthogonal channel. The manufacture of separators by this new extrusion method was successful. Moreover, it is important to determine the most suitable speed condition for stable extrusion.
