Abstract

A fibrous sheet for fuel cell or battery applications is formed by electrospinning a fluorinated ion-conducting polymer solution to form an agglomeration of fibers.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of US Provisional Application No. 61 / 413,688, filed November 15, 2010, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to methods for making fuel cell membranes, gas diffusion media, fuel cell electrodes and battery separators. Background technique [0004] In battery applications, perforated plates are used as separators. A battery separator is a porous plate that is inserted between an anode and a cathode in a fluid electrolyte. For example, in lithium-ion batteries, lithium ions (Li + ) moves from the anode to the cathode during discharge. The battery separator serves to prevent direct contact of the electrodes while allowing ions to be transferred. Typical prior art separators include microporous membranes and mats made from nonwovens. A battery separator is ideally inert to the electrochemic...
