Abstract In this paper, a photocatalytic fuel cell system was designed using a high-performance TiO2 nanopore array electrode as anode and a Pt-black/Pt electrode as cathode for generation of electricity and simultaneously wastewater treatment. Various model compounds including the refractory compounds as well as real wastewater samples were used as substrate for the PFC system. The results showed that the PFC generated the excellent cell performance,for example,when acetic acid(0.05mol /L) as the substrateof the PFC, produces open-circuit voltage (Voc)1.16V, short-circuit current density (Jsc) 1.28 mA /cm2 and maximum power density( (JV)max) 0.28mW/cm2.
