A Theoretical Study on Photocatalytic Fuel Cell

This paper presents a theoretical study which investigates the detail potential loss within photocatalytic fuel cell (PFC). Ohmic loss in PFC contributes to 24% potential loss since the large electrical resistance of semiconductor. It is found that Schottky barrier height plays an important role on performance of PFC, and Schottky barrier height of 0.6 eV is preferred for PFC operation. Moreover, current will be enhanced with the activity of photocatayst increasing.
