Abstract:
A proton exchange membrane comprises a hybrid inorganic-organic polymer that includes implanted metal cations. Acid groups are bound to the hybrid inorganic-organic polymer through an interaction with the implanted metal cations. An example process for manufacturing a proton exchange membrane includes sol-gel polymerization of silane precursors in a medium containing the metal cations, followed by exposure of the metal-implanted hybrid inorganic-organic polymer to an acid compound.
