Abstract: This paper presents seven types of biological hydrogen production systems and the mechanism，affecting factors，methods of enhancement of hydrogen production as well as research progress. The recent studies are focused on photo fermentation and anaerobic fermentation technology. Anaerobic fermentation systems have the great potential to be developed as practical biological hydrogen systems due to its high hydrogen yield. A hybrid system using photosynthesis and fermentative bacteria can enhance the hydrogen production and reduce the need for light. The process will be the future direction of biological hydrogen production.

摘要： 阐述了7类生物制氢系统的产氢机理、影响因素以及提高产氢率和产氢量的方法，介绍了国外最新的研究进展。光发酵生物制氢技术和厌氧发酵生物制氢技术是研究的热点，而厌氧发酵由于产氢效率较高而成为最具潜力的生物制氢技术之一。光合–发酵杂交技术不仅减少了所需光能，而且增加了氢气产量，同时也彻底降解了有机物，使该技术成为生物制氢技术的发展方向。
