随着经济的飞速发展，社会对能源的需求日益扩大，对工业废水的无害化处理也提出了更高的要求。光催化燃料电池(photocatalytic fuel cell, PFC)在燃料电池中引入半导体光催化材料作为电极，实现了有机污染物高效降解和同步对外产电的双重功能，在废水无害化与资源化利用方面具有潜在的应用价值。半导体光催化电极是PFC系统高效运行的核心组件，增强其可见光响应和光生载流子分离是提高PFC性能的关键策略。反应器结构设计和运行参数优化也有利于改善PFC性能。本文从PFC基本原理和应用入手，综述了PFC在环境污染物资源化处理中的研究进展，并详细阐述了提高PFC的污染控制性能和产电效率的优化手段，为进一步设计高效稳定的PFC系统并实现其在水污染控制和清洁能源生产中的应用提供理论指导。

The social demand for energy is highly increasing because of the rapid development of economy. On the other hand, environmentally safe treatment of industrial wastewater is required to raise to a higher standard. Photocatalytic fuel cell (PFC), which adopts the photocatalytic electrode in the fuel cell configuration, can achieve the dual functions of efficient degradation of organic pollutant and simultaneous electricity generation. Therefore, PFC promises to have potential applications in harmless disposal and resource utilization of wastewater. The photocatalytic electrode is the core component of PFC system. The enhancement for the light activation of the photocatalytic electrode and the improvement of the separation rate of photogenerated carriers become the key strategies to improve the performance. In addition, the reactor design and optimization of operational parameters are also beneficial to improve the PFC performance. In this review, the basic principle of PFC has been introduced, and the progress of PFC in the treatment of environmental pollutants has also been reviewed. The optimization of PFC system for enhancing the pollution control performance and electricity generation efficiency has also been discussed in detail. This review provides theoretical guidance for further research of efficient and stable PFC systems for the wastewater treatment and energy recovery.
