Membranes and electrochemical devices including them

摘要

A material comprises an electronically conducting polymer (ECP) and an ionically conducting polymer (ICP) which are interlinked. Preferably the ionically conducting polymer (ICP) is hydrophilic and the electronically conducting polymer is polyacetylene, PEDOTTSS or polyaniline. Advantageously the material may be used as a membrane electrode assembly where the ionically conducting material is a membrane suitable for use in electrochemical cells including electrolysers and fuel cells and junctions between biological systems and electronic devices such as a nerve-contacting prosthesis.
