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.
