A Case Studying of Nature Light Source with Hydrogen Quantity Used in Small-Sized Regenerative Fuel Cell

This paper presents a case studying of nature light source with hydrogen quantity used in small-sized regenerative fuel cell, by studied the natural sunlight in the second time period between 08.30 to 12.00 am, and 13.30 to 17.00 pm, with artificial light source which was conducted in room drapes. The light energy to the polycrystalline silicon solar cell with size 2.5 volt 11 watt panel, that acts of voltage to electrolyzer which water is separated, into hydrogen and oxygen to keep the barrel to collect feedback into the fuel cell to generate electricity. The study found that natural sunlight the performance to split water with electricity is a better at the time of maximum light intensity, an increasing proportion of the size of the light intensity in the range of the 1 to 3 times the amount of hydrogen.
