  • Formation of hydrophilic polymer membranes using a bronsted base
    Patent number: 9559373
    Abstract: A method of forming a hydrophilic polymer is disclosed. The method can include: reacting a monomer comprising an acid group with a Bronsted base to form an ionic liquid; polymerizing the ionic liquid with at least one other monomer; and converting the ionic liquid back to the acid group after polymerization. Also disclosed are hydrophilic polymers and membrane electrode assemblies formed using the above method.
    Type: Grant
    Filed: May 30, 2014
    Date of Patent: January 31, 2017
    Assignee: ITM POWER (RESEARCH) LIMITED
    Inventors: Daniel Greenhalgh, Rachel Lister
  • High water-content membranes
    Patent number: 9553319
    Abstract: The present invention is a hydrophilic polymer, which can be hydrated to form a hydrated hydrophilic polymer having a water content of at least 65%, wherein water content is defined as [(mass of the hydrated hydrophilic polymer?mass of the dry hydrophilic polymer)/mass of the hydrated hydrophilic polymer]×100. The hydrophilic polymer may be hydrated to form a hydrated hydrophilic polymer having a water content of at least 65%. The present invention also 10 provides MEAs and electrochemical cells and methods of forming same.
