Abstract
This invention concerns a high temperature fuel cell with mixed anionic and protonic conduction having a protonic conduction reforming membrane directly coupled to a solid oxide fuel cell with conduction by oxygen ions, enabling use of a gradually reforming anode generating carbon deposits to be avoided. The reverse operation of the present invention outside the reforming stage forms a high water temperature electrolyser to produce hydrogen efficiently without having to separate it from water as is the case with current systems.
