Plasma-polymerized thin films as new membranes for miniature solid alkaline fuel cells

The synthesis by plasma polymerization of dense materials containing hydroxyl exchange amine functions has been demonstrated. The optimization of the synthesis parameters has enabled to manufacture micrometric membranes showing satisfying anionic conductivity. For the future, we envisage to deposit such membranes on the surface of electrodes also synthesized by a plasma process in order to manufacture entirely integrated “plasma fuel cells”.
