Solid polymer electrolyte proton conductors for use in electrochemical systems working at ambient temperature

摘要

An electrochemical system operating at ambient temperatures comprises: (i) anode (12) and cathode (14) plates; (ii) a non- liquid proton conductor membrane (16) between the plates, so that an electrical contact is formed with ions flowing between, the membrane including (a) a matrix polymer dissolvable in a solvent; and (b) an acidic multimer dissolvable in the same solvent. (a) is selected such that when the membrane is contacted with a second solvent, the membrane swells to improve the electrical contact.
