1. A method of making a device with a fibrous sheet, the method comprising:
- providing a solution comprising a fluorinated polymer;
forming an aggregation of fibers, the aggregation of fibers formed by electrospinning the solution of a fluorinated ion conducting polymer;
forming the fibrous sheet from the aggregation of fibers;
mechanically compacting the fibrous sheet to increase fiber density;
welding fibers together at fiber intersection points by exposing the fibers to a solvent vapor; and
interposing the fibrous sheet between an anode and a cathode.
