在全球能源危机的推动下，全球对制氢的兴趣不断增加。目前，美国超过95%的氢气供应来自不可再生材料，包括煤炭，石油和天然气。与化石燃料使用相关的环境压力的补救需要从可再生能源（例如太阳能、风能和生物质）生产氢。最近发明的微生物电解技术展示了从可再生生物质可持续制氢的新途径。它有可能成为一种经济可行的制氢方法，因为与发酵制氢相比，它的产氢率高，与水电解制氢相比，它的能量需求低得多（理论上约10%）。在这一章中，我们开始与微生物电解池（MEC）和化学计量学和能量学的介绍，其次是在MEC和他们的合理的电子转移机制的微生物的一节。最先进的设计，操作和评价的MEC也进行了讨论。
Driven by the world-wide energy crisis, global interest in hydrogen production continues to increase. Currently, over 95% of the hydrogen supply in the USA is derived from nonrenewable materials, including coal, oil, and natural gas. Remediation of environmental stress related to fossil fuel use requires hydrogen production from renewable energy sources, such as solar, wind, and biomass. A recently invented microbial electrolysis technology demonstrates a new avenue for sustainable hydrogen production from renewable biomass. It has potential to become an economically feasible approach for hydrogen production due to its high hydrogen yield compared to fermentative hydrogen production and much lower energy requirement (about 10% in theory) compared to hydrogen production via water electrolysis. In this chapter, we begin with an introduction of microbial electrolysis cells (MECs) and the stoichiometry and energetics, followed by a section on the microorganisms in MECs and their plausible electron transfer mechanisms. The state-of-art designs, operation, and evaluation of MECs are also discussed.
