<p>The invention relates to a hydrogen generator producing it from water, by using microwaves, and to an autonomous hydrogen-producing station using the same. According to the invention, the hydrogen generator comprises a microwave generator (A) with simple or multiple waveguide (1) and magnetron (2), and at least one electrolyser (B) with solid electrolyte, coupled with the open end of the waveguide (1) by a horn-antenna (4) containing balls (b) or porous ceramics or corundum particles (b'), in order to convert the water fed thereinto by a nozzle (3) with an electrically-operated valve (5), the electrolyser (B) comprising within a ceramic or metallic tank (6) some porous metallic electrode-plates (7 and 7') made of Ni or stainless steel with Ni, provided with some extensions (h) for electrical connection, fixed in an insulating support (i), between the electrode-plates (7 and 7') there being placed two or three successive layers (m, m' and m'), as follows: a first insulating layer (m) made of porous ceramic balls, a second semiconductor layer (m') made of silicon carbide and a third conductor layer (m') made of metal powder of Ni or steel with Ni, within the third layer (m') there being placed some thin separating blades (12) of porous ceramics, each of them being plated on its face with a coat (n and n') of porous Ni and fixed in the support (i) in which there is also fixed a micro porous membrane (9) permeable only for the produced Brown gas, and an insulating plate (10) for separating the electric connections of the extensions (h), the so produced Brown gas being collected through an outlet (l) from an electrically insulating cap (11), positioned between the insulating plate (10) and the membrane (9). The hydrogen station uses generators with two horn-antennas (4 and 4') with electrolysers (B and B') coupled to a waveguide (1) opened at both ends and is supplied with electric power produced by a wind turbine (D) or by a solar panel (19).</p> |
