Abstract

A polymer electrolyte membrane assembly includes a polymer electrolyte membrane layer positioned between a first electrode and a second electrode. The polymer electrolyte membrane layer can be made from a composition including a polymer matrix, a plasticizer, and an ionic material. The polymer electrolyte membrane assembly may be utilized to harvest electrical energy by allowing the polymer electrolyte membrane assembly to bend to thereby produce a second ion concentration gradient different from an initial ion concentration gradient.
