Photocatalytic fuel cell for wastewater treatment and recovery of energy resources
P
hotocatalytic fuel cell (PFC) is primarily a synergistic integration of two emerging technologies, namely, photocatalysis
(PC) and fuel cell (FC). Solar PC can decompose organic compounds while FC provides an electrical potential gradient
to facilitate transport of electrons. Therefore, PFC can be effectively applied to utilize solar energy for wastewater treatment
and recovery of energy chemically stored in wastewater. It is a promising technology for solving both environmental and
energy problems. In order to conduct proper research for rapid development of PFC, we need to have good knowledge about
the material properties and clearly understand the cell mechanisms of PFC. The Fermi level between the photoanode and the
cathode forms interior bias that inhibits recombination of photogenerated electrons and holes, resulting in increase in visible-
light activation of PFC. Modification of photoelectrocatalysts and use of microfluidics are effective strategies for improving the
PFC performance. The PFC effects can also be manipulated by the system configuration, design and control for specific outputs
and reaction rates. The speaker will present the fundamentals, latest development of PFC and upcoming R&D challenges
needed for enhancing the PFC technology.
