A device for the thermal separation of water into hydrogen and oxygen, including a closed reaction chamber (1) containing water and, in said reaction chamber: - a heating system including one or more heat source elements (4,11), - one or more essentially gas-tight membranes (3) selectively enabling the passage of oxygen, - one or more essentially gas-tight membranes (2) selectively enabling the passage of hydrogen and - a mechanism (5) enabling the ingress of water into said reaction chamber. According to the invention, - said heat source(s) (4, 11) is(are) placed in the water inside said reaction chamber (1), and, - said membranes (3) selective for oxygen are placed in said zones at high temperatures, - said membranes (2) selective for hydrogen are placed in said zones at lower temperatures. Preferably, the heating system is comprised of one or more solar radiation concentrators (8, 9) focusing the radiation on the inside of the reactor. |
