1. An electrochromic device comprising a solid layered structure, said structure including a pair of electrodes and an electrochromic layer sandwiched between said pair of electrodes, in combination with:
- a pair of vitreous sheets of which at least one is transparent, said device being sandwiched between said pair of vitreous sheets; and
a reservoir of ionisable material held between said sheets, said reservoir being a gas-filled space within said device and being a controlled-humidity source of H+ ions, wherein on the application of an electrical potential between said pair of electrodes, ions are permitted to migrate between said ionisable material and said electrochromic layer.

Abstract
An electrochromic device comprising a solid layered structure. The structure includes a pair of electrodes and an electrochromic layer sandwiched between the pair of electrodes. The device is sandwiched between a pair of vitreous sheets of which at least one is transparent with a reservoir of ionizable material being held between the sheets. On application of an electrical potential between the electrodes, ions are permitted to migrate between the ionizable material and the electrochromic layer.
