Popis: Integration of fuel cells for nomad applications (like cell phone or notebook) is characterized by small dimensions and high performances of the component. To obtain theses properties, one of possibilities is to increase the active surface with patterned substrate. Then, the actual planar batteries must be replaced by 3D batteries. Most of deposition methods, used in the actual fuel cell process flow, are not compatible with the 3D deposition because they did not provide conformal coating. That is why we develop a PECVD electrolyte because this method is known to be compatible with 3D depositions. The PECVD electrolyte is based on a fluorocarboxylic acid, which is able to conduct protons. The obtained layer is a protonic conductor that can absorb water and stop hydrogen. Effects of elaboration parameters like pressure, power, or acid concentration on the ionic conductivity will be presented.
