HYDROGEN GENERATION SYSTEM

摘要

A system (1) for generating hydrogen using solar energy. The system comprises an electrolyser (14) which comprises a photocatalyst arranged to generate hydrogen from an electrolyte (e.g. water) on illumination with solar radiation (15). The system also comprises a photovoltaic cell (6) arranged to generate a bias voltage on illumination with solar radiation (7) and means for applying the bias voltage to the electrolyser (14). The system further comprises at least one solar concentrator (2) arranged to concentrate incident solar radiation (3) onto the electrolyser (14) and the photovoltaic cell (6).
