Multi-layer polymer electrolyte-membrane, electrochemical apparatus and process for the preparation of multi-layer polymer electrolyte membrane

摘要

A multi-layer polymer electrolyte membrane having a polymer electrolyte layer and a porous polymer electrolyte layer with three dimensional network pores on the former polymer electrolyte layer is provided. The polymer electrolyte layer can be provided on both sides of the porous polymer electrolyte layer. An electrochemical apparatus and a solid polymer electrolyte type fuel cell made of the multi-layer polymer electrolyte membrane can be provided. Further, a solid polymer electrolyte type fuel cell having the multi-layer polymer electrolyte membrane can be provided. Further, a process for the preparation of the multi-layer polymer electrolyte membrane can be provided.
