Abstract

Ένα υδρόφιλο διασταυρωμένο πολυμερές το οποίο μπορεί να ληφθεί με συμπολυμερισμό υδρόφοβων και υδρόφιλων μονομερών που δίδουν ένα διασταυρωμένο υδρόφιλο πολυμερές κατά τον πολυμερισμό- ένα μονομερές που περιλαμβάνει μία έντονα ιοντική ομάδα- και νερό, είναι χρήσιμο ως μεμβράνη σε ένα συγκρότημα το οποίο μπορεί να χρησιμοποιηθεί σε μία διάταξη ηλεκτρολύσεως ή σε ένα στοιχείο καυσίμου. Γενικότερα, ένα συγκρότημα ηλεκτροδίων μεμβράνης περιλαμβάνει ηλεκτρόδια και μία ιοντο-εναλλακτική μεμβράνη η οποία περιλαμβάνει ένα υδρόφιλο πολυμερές που διαθέτει μία έντονα ιοντική ομάδα. Μία μέθοδος παραγωγής ενός συγκροτήματος ηλεκτροδίων μεμβράνης το οποίο διαθέτει ηλεκτρόδια και μία ιοντο-εναλλακτική μεμβράνη, περιλαμβάνει την εισαγωγή μεταξύ των ηλεκτροδίων ενός υλικού ή υλικών από τα οποία μπορεί να διαμορφωθεί η μεμβράνη, και τη διαμόρφωση της μεμβράνης επιτόπου.
