Abstract:

A novel photocatalytic fuel cell using water soluble polyoxometalates(POM) as photocatalyst and charge carrier was built. The fuel oxidation in this study is a homogeneous decomposition reaction that occurred in electrolyte solution and the cell could generate electricity in dark. Using bio-glycerols as fuels, the power density of the photocatalytic fuel cell could reach 0.24 mW/cm2. The cell worked steadily for nearly 50 h with current above 0.75 mA under continuous irradiation. Theoretically, the glycerol fuel can be either partially converted to aldehydes and acids, or fully converted to COx, depending on the degree of the oxidization reactions. Ultimately, this novel photoactivated hybrid fuel cell could expand fuel supply and utilization.
