Polymer Membranes – Sandia National Laboratories
Polymer membranes play a crucial function in many energy and water technologies, including energy storage, water electrolysis and purification, and stationary and transportation power systems. The membranes are tailored to allow conduction of specific ionic species between the negative and positive electrodes in an electrochemical system. For example, polymer membranes can be optimized for transport of protons (H+) or hydroxyl ions (OH-), depending on the acidic or alkaline environment of the energy-water system. The prototype poly (phenylene)-based hydrocarbon membrane separators developed at Sandia National Laboratories are showing exceptional performance in real-world application tests by system customers and partner research institutions.
