Abstract
Disclosed is the use of liquid precursor materials to prepare a processible polymeric electrolyte, which can be used to form a proton exchange membrane for use in an electrochemical cell. Also disclosed is the use of liquid precursor materials to prepare a processible catalyst ink composition, which can be conformally applied to a proton exchange membrane and a electrode material for use in an electrochemical cell. Also disclosed is the use of a photocurable perfluoropolyether (PFPE) material to form a microfluidic electrochemical cell.

A polymeric electrolyte membrane, comprising:
- a polymerized 100% solids liquid precursor material, wherein prior to polymerization the 100% solids liquid precursor material is a liquid at about 40 degrees Celsius.
A polymeric electrolyte membrane, comprising a fluoropolymer membrane having an equivalent weight of less than 850.
A membrane, comprising:
- a polymerized 100% solids liquid precursor material comprising greater than about 50% by weight of a sulfonic acid precursor and less than about 50% by weight of a fluoropolymer, wherein the membrane has a conductivity of greater than about 0.14 S/cm when fully hydrated.
