PHOTOCHEMICAL SEMICONDUCTOR ELEMENT THAT ACCUMULATES HYDROGEN

摘要

The proposed photochemical semiconductor element that accumulates hydrogen contains an accumulating electrode and a photoanode. The accumulating electrode is made of LaNi2,5Co2,4Al0,1 alloy that absorbs hydrogen. The photoanode is made of gallium arsenide with electron conductivity, with a surface layer alloyed by platinum. The accumulating electrode is installed in the chamber that is filled with alkaline solution and separated from the anode chamber by a cation-exchange diaphragm. The photoanode is installed in hyposulfide solution. The proposed element can be used in plants for converting solar energy into chemical energy of hydrogen.
