Nanochannel arrays as supports for proton exchange membranes

Proton exchange membrane (PEM) can be created by using sodium silicate in nanochannel array that connect two microfluidic channels used for fuel cell. Sodium silicate based sol-gel structure thus bridges cathodic and anodic compartments. Scientists from Dutta Research Lab at University of Wyoming were able to generate an open circuit potential of 1.31V and a maximum current of 31.2 uA at room temperature. Study is recently published in the Journal of Power Science. Click on the link to see the journal article.
