Claim:
1. A method of thermally protecting an object, comprising protectively associating with the object to be protected an all-solid electrochromic device with controlled infrared reflection or emission, said device comprising a stack, said stack successively comprising from a back face towards a front face exposed to infrared radiation: a) a substrate made of an electron-conducting material, or a substrate made of a non-electron-conducting material coated with a layer made of an electron-conducting material, said substrate made of an electron-conducting material or said layer made of an electron-conducting material forming a first electrode; b) a layer made of a first proton storage electrochromic material; c) a layer of a proton-conducting and electron-insulating electrolyte; d) a bilayer comprising a layer of a non-electrochromic, sub-stoichiometric tungsten oxide, WO e) a protective layer transparent to infrared radiation, made of an inorganic material.
