| 摘要 |
The present invention relates to a method of producing hydrogen comprising: contacting steam 20 with a proton conducting membrane 7 supported on a porous redox stable substrate 8 , through said substrate 8 . The membrane 7 is non-permeable to molecular gas and to oxide ions. A DC voltage is applied across an anode 15 coupled to the substrate side of the membrane and a cathode 9,11 coupled to its other side so as to dissociate at least part of the steam 20 , into protonic hydrogen and oxygen at said anode 15 . The protonic hydrogen passes through the membrane and forms molecular hydrogen 23 at the cathode 9, 11.
