DIRECT COUPLING DEVICE FOR GENERATING HYDROGEN FROM CONCENTRATED SUNLIGHT

摘要

The invention relates to a direct coupling device (31) for generating hydrogen from concentrated sunlight, said device comprising a solar concentrator and converter (32) and a water electrolyser (33), the solar concentrator and converter (32) comprising an optical concentration element (15) adjacent to a number of photovoltaic cells (14) coupled to a heat exchanger (13), and the water electrolyser (33) comprising a proton exchange membrane (2) in which the membrane has a number of individual anode zones (6) and cathode zones (12) coated with a catalyst, a number of single-pole cathode plates (3) and a number of single-pole anode plates (5), a number of regeneration electrodes (1), a number of floating flow guide plates (7), a number of elastic compression elements (8) and a casing consisting of an upper part (9) and a lower part (10).
