P.E.M`s (fuel cell)

YT2095 - 4-7-2007 at 05:08

I have a couple of fuel cells here already but they are only tiny, one is a Fuel cell/Electrolyser also.

I`m hoping to replicate this principal in the Lab, tweek it so that I can get best performance and then hopefully scale it up a little.

Has anyone ever taken apart a Lithium Battery, in particular a CR123A or similar?

inside you will not that they are spiral wrapped like an electrolytic capacitor or a Ni-Cad, the Anode is the MnO2 on a metallic substrate, and the Cathode is the Li metal as a foil.

there is no Direct electrolytic contact, they are seperated by a White Very thin Plastic like material that strongly resembles PTFE.

Does anyone know what this material is made of and is it a Proton or Ion Exchange Membrane?
