ABSTRACT:
A multielectrode photoelectrochemical cell in which at least contains two bipolar electrode panels for photoelectrochemical reactions such as water photolysis to produce H.sub.2 O.sub.2 without external bias. In one embodiment of the present invention, a bipolar TiO.sub.2 /Pt multielectrode photoelectrochemical cell was fabricated with five panels in series. The cell permitted unassisted photolytic (Xe lamp) water splitting to produce H.sub.2 and O.sub.2 with H.sub.2 O.sub.2 molar ratio of 2.4/1.
