In this work, a photocatalytic fuel cell (PFC) with membrane electrode assembly (MEA) structure was designed for simultaneous organic compounds degradation and electricity generation. For the photoanode, the TiO2 with the quantum-dot sensitization by CdS-ZnS was used to broaden the absorption spectrum to visible light. For the cathode, an air-breathing mode was utilized to enhance the oxygen transport. The performance of the developed PFC was evaluated under different operation conditions, including the light intensity, liquid flow rate, concentrations of electrolyte and organics. Results indicated that the designed PFC could yield good performance. The increase of the light intensity and electrolyte concentration could improve the PFC performance. It is also found that when the flow rate was increased, the PFC performance dropped down in the testing range. Too high organics concentration led to the decrease of the PFC performance.

In this work, the control of the droplet generation by a focused infrared (IR) laser with a wavelength of 1550 nm was studied, in which the liquid water and the oil with the surfactant of Span 80 were employed as the disperse and continuous phases, respectively. The characteristics of the droplet generation controlled by the laser was explored under various flow rates, laser powers and spot positions and the comparison between the cases with/without the laser was also performed. The results showed that when the laser was focused on the region away from the outlet of the liquid water inflow channel, the droplet shedding was blocked due to the IR laser heating induced thermocapillary flow, leading to the increase of the droplet volume and the cycle time of the droplet generation as compared to the case without the laser. Decreasing the continuous phase flow rate led to the increase of the droplet volume, cycle time of the droplet generation and the volume increase ratio, while increasing the disperse phase ...
