ABSTRACT

Photocatalytic fuel cell (PFC) is a synergistic integration between two emerging technologies, namely, photocatalysis (PC) and fuel cell (FC) technologies. The PFC activity depends highly on the nano-structure (morphology and dimensions) of the photocatalyst and the micro-scale design of the fuel cell. Recent studies have demonstrated the effectiveness of the new PFC approach in solving environmental and energy problems. A solar PFC can decompose organic compounds in wastewater for wastewater treatment and simultaneously produce electricity or renewable hydrogen fuel. The dual benefits are particularly valuable for remote areas where energy sources are scarce for the residents. PFC is also applicable to food waste, agricultural residues, sludge, industrial organic waste, etc. The potential of a PFC is enormous. In this chapter, we present the photocatalytic electrochemical mechanisms of PFC and its development.
