perfluorinated Ion exchange Film, high temperature fuel cell membrane N31x
FULEL CELL N-31X (SiO2)
Perfluorinated Ion exchange Film
Introduction :
N-31x(SiO2) is hybided bySiO2 and Perfluorinated ion exchange Resin .
It not only has the high tensile strength ,high selection,isotropy,high conductance;but also has the effect of self-humidifying and with low Linear Expansion.
It can be used in hight temperature fuel cells and self-humidifying fuel cells.
Package:
N N-31x(SiO2) is packed by plastic bucket .Special package please indicate.
