Outline of Final Research Achievements

The energy system with the solar cell, poly-silane-metal catalyst and direct fuel cell is proposed. This method consists of the following steps. First, the water was efficiently decomposed by the electrical power generated using solar cells. The developed high efficiency and low cost solar cells are one of the candidates to generate hydrogen molecules with the low cost enough for the future energy market. The generated hydrogen molecules were catalyzed using the poly-silane Pd catalyst to hydrogenate the carbonyl groups of benzoquinone, resulting in making it hydroquinone. The solar energy was stored as a chemical storage of hydrogen as OH in the molecules. This storage energy in the molecules was converted to the electrical power using the direct fuel cell, where the hydroquinone was oxidized to benzoquinone. This system will solve the instability problem of renewable energies.
