Fundamental study on solar thermal cell
Solar thermal cell converts low-temperature solar thermal energy into electric power. It bases on the principle of fuel cell with 2-propanol dehydrogenation and acetone hydrogenation. As the fundamental experiments, acetone was diluted with water and supplied to positive electrode. In case of liquid-phase solar thermal cell, 2-propanol was supplied to negative electrode directly. In case of gas-phase solar thermal cell, hydrogen gas was supplied to negative electrode as proton source. The authors investigated effects of 2-propanol concentration, catalyst loading and reaction temperature on the cell efficiency. When 2-propanol was diluted with water and supplied to negative electrode, it was shown that 2-propanol concentration of 50--70 vol% was the best for cell efficiency. The cell efficiency was improved with increasing catalyst loading. As for reaction temperature, 80 C was better to improve the efficiency.
