Abstract
The invention relates to a fuel cell and an electrochemical cell comprising a curable perfluorosulfonate ionomer based electrolyte composition. The electrolyte composition comprises between 10 wt % and 50 wt % of a perfluoro-sulfonate ionomer (PFSI) comprising acidic groups for transporting protons; between 10 wt % and 89 wt % of a monomer for dissolving the PFSI; between 1 wt % and 60 wt % of a cross linking agent having at least two vinyl functionalities; and wherein upon combining the PFSI, monomer and cross linking agent, a curable electrolyte solution is formed with at least 50 wt % of the above components based on the total weight percent of the formed solution. The invention relates to a method for producing the curable liquid electrolyte.
