The invention relates to a process for preparing proton-conducting clay particles, successively comprising the following steps: Use of these particles for the manufacture of fuel cell membranes.

Process for preparing proton-conducting clay particles and composite material comprising such particles

The present invention concerns a flexible electrochrome structure operating in reflection at wavelengths between 0.35 and 20 &mgr;m. It comprises a microporous membrane including an electrolyte and, deposited on each of the surfaces of the microporous membrane, in a symmetrical manner in relation to said membrane, successively and in this order: a layer forming a reflecting electrode, a layer of electrochrome conductive polymer, and a flexible window transparent to wavelengths between 0.35 and 20 &mgr;m.

Flexible electrochrome structure and methods for the production thereof

Process for charging a structure formed from an insulating body sandwiched between two electrodes. In the process a Faraday cage is placed in contact with one of the electrodes of the structure, the potential of the other electrode being made equal to a reference potential. Electrons originating from a controlled electron emission device are introduced into the Faraday cage, the electrons reaching the electrode with which the Faraday cage is in contact to charge the structure. Such a process may find particular application for determining properties of insulating materials.
