An ion-exchange material is typically modeled as a porous medium consisting of a fixed matrix with the pores filled up with water and additional mobile ions. This may sound completely wrong to anyone who has seen, for instance, a Nafion® membrane, one of the most common polymer electrolyte...
eVent clothing works in a similar way to GORE-TEX: it has three layers of fabric, with a backing fabric on the inside, a wicking Teflon-type (PTFE) membrane in the middle to draw moisture away, and a water-repellent outside.SympaTex is quite different. Instead of having micropores, ...
PEM electrolyzers, using a thin solid polymer electrolyte (membrane, mainly Nafion®) instead of a liquid electrolyte, are a newer generation of electrolysis systems compared to alkaline electrolyzers. The solid membrane results in a compact design, high current density, faster response to load ...
It was recently shown [95] that all the spectra can be assigned as a mixture of on-top, twofold bridging and threefold bridging hydrogen in ~1:2:1 ratio. The membrane that separates the anode and cathode in a PEMFC is a crucial component. This is usually Nafion, a polymer consisting ...
