光生物反应器的设计，可以克服光穿透，搅拌和温度控制差的光发酵产氢的挑战。据报道，平板反应器具有优于其他反应器的几个优点。但是当将其用于制氢时，它们限于合适类型的搅拌系统。本研究的目的是开发和改进一种平板反应器，可以克服与摇摆运动搅拌的问题。球形红细菌的研究001的最大产氢速率为11 mL L-1 h（-1），底物（苹果酸）转化效率为44.4%，光转化效率为3.31%，累积产氢量为492 ± 10 mL。发现反应器的混合时间约为17 s，功率输入为100-275 W/m（3）。虽然整个反应堆都在运动，但发现用于摇摆运动的能量相当低。版权所有（C）2010，氢能出版有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Photofermentative hydrogen production is challenged by the photobioreactor design that can overcome poor light penetration, agitation and temperature control. Flat panel reactors have been reported to have several advantages over other reactors. But they are limited to a suitable type of agitation system when using it for hydrogen production. The aim of the present study is to develop and improve a flat panel reactor that can overcome the problem of agitation with a rocking motion. Studies with Rhodobacter sphaeroides O.U. 001 resulted in a cumulative hydrogen production of 492 +/- 10 mL with maximum production rate of 11 mL L-1 h(-1), substrate (malic acid) conversion efficiency of 44.4% and light conversion efficiency of 3.31%. The mixing time of the reactor was found to be around 17 s with a power input of 100-275 W/m(3). Though the entire reactor was in motion the energy spent for the rocking motion was found to be quite low. Copyright (C) 2010, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
