Background technique

With the development of society and the progress of science, electricity is becoming more and more important in people's social life. However, with the increasing depletion of traditional energy sources such as petroleum and coal, it is necessary to develop new energy sources to convert them into electric energy. Hydrogen energy is becoming more and more clean and efficient. , Wide source, recyclable, pollution-free and other advantages have won the favor of people. The most mature method for converting hydrogen energy into electricity is fuel cells. Ordinary fuel cells use hydrogen to be oxidized, and oxygen is reduced to generate water to convert hydrogen energy. for electrical energy.

However, there are a large number of industrial hydrogen production methods including water electrolysis, water gas hydrogen production, and hydrogen production from synthetic gas and natural gas from thermal cracking of petroleum. These hydrogen production methods have the characteristics of high energy consumption and many by-products. There is also a photosynthetic biological hydrogen production method. Although compared with electrolysis and water gas hydrogen production, the hydrogen production rate is fast, the purity is high, and the energy consumption is small. However, it is inconvenient and practical to require long-term illumination. In recent years, the hydrogen production of dark fermentation bacteria has emerged, which is a process of converting organic matter into biological hydrogen in three steps by using a bacterial group multi-enzyme system, similar to anaerobic conversion. The dark fermentation reaction does not require light energy, so it can use organic compounds to produce hydrogen day and night. Therefore, the hydrogen production efficiency is fast, the substrate conversion rate is high, and various industrial and agricultural wastes can be used.

In addition, the reduction of oxygen is slow, the power generation efficiency is low, and the utilization rate is not high. Therefore, the reduction reaction can be changed so that the reduction of ferric iron to ferrous iron is much faster, and the aerobic metabolism of microorganisms such as iron-reducing bacteria can be used to recycle ferrous iron into ferric iron. Such a new type of fuel cell realizes an efficient and environmentally friendly process of generating hydrogen energy and efficiently converting it into electric energy.
