    • The invention relates to a device for splitting water into hydrogen and oxygen by thermolysis, that is, by decomposition at elevated temperature. This device comprises: - a reactor (1) having a heating system (2), a first reactor outlet (3), a second reactor outlet (4), at least one water inlet (5) and at least one oxygen filter (6); - at least one hydrogen filter (7); - an oxygen extraction pump (8), a hydrogen extraction pump (9), at least one water injection pump (10); - a hydrogen separation chamber (11) located outside the reactor (1) and containing the hydrogen filter(s) (7); - a heat exchanger (15) comprising an inlet (31) and an outlet (13) for a first circuit and an inlet (17) and an outlet (19) for a second circuit. The particularity of such a device is that it comprises two further heat exchangers (16, 28) each comprising an inlet (14, 27) and an outlet (20, 29) for a first circuit and an inlet (22, 36) and an outlet (23, 34) for a second circuit and in that: - the inlet (31) of the first circuit of a first heat exchanger (15) is connected to an external water inlet (12) via the water injection pump (10), the outlet (13) of the first circuit of the first heat exchanger (15) is connected to the inlet (14) of a first circuit of a second heat exchanger (16); - the inlet (17) of the second circuit of the first heat exchanger (15) is connected to an outlet (18) of the hydrogen separation chamber (11), which is connected to the filter(s) (7) and the outlet (19) of the second circuit of the first heat exchanger (15) is a hydrogen outlet of the device. The invention also pertains to a process for splitting water into hydrogen using the above device.
