Leak Proof / Water tight Gas Diffusion Layers

We have been getting more questions and requests regarding Gas Diffusion Layers (GDL) that are water proof or which do not allow water to seep or leak through them. ┬áThis is especially of interest when building Magnesium Air Batteries (also known as Magnesium Air Fuel Cells), Microbial Fuel Cells (MFC), and a host of other electrochemical reactions with a liquid electrolyte that needs access to gas or oxygen.Most GDL materials have a high air permeability that also results in at least some … [Read more...]
