3D-printed proton-conductive membrane paves way for tailored energy storage devices

The advent and increased availability of 3D printing is leading to more customizable parts at lower costs across a spectrum of applications, from wearable smart devices to autonomous vehicles. Now, a research team has 3D printed a proton exchange membrane, a critical component of batteries, electrochemical capacitors and fuel cells. The achievement also brings the possibility of custom solid-state energy devices closer to reality, according to the researchers.
