Scientists from Vernadsky Institute of General and Inorganic Chemistry and Frantsevich Institute for Problems of Materials Science of National Academy of Sciences of Ukraine have developed Experimental photoelectrochemical cell for hydrogen accumulation under the action of sunlight. When the anode of this device is exposed to Sun, its cathode starts to produce hydrogen via photoelectrochemical reactions.
Such system can be used to generate hydrogen, which can be transformed later into electricity in a fuel cell, where hydrogen is oxidized by oxygen from air. It can be also used as a photoaccumulator, which will ensure uninterrupted power supply of consumers under conditions of changing light intensity.
