BIOELECTROCHEMICAL HYDROGEN-PRODUCTION

The presented method of hydrogen production by biological means is bas ed on a combination of bioelectrochemical fuel cells with an electroly zer, the fuel cells generate the electric energy required for the elec trolysis of water. This approach makes it possible to utilize widespre ad redox reactions of the microbial energy metabolism, whereas most of the methods of biological hydrogen production known to date are limit ed to the reactions of hydrogenases or nitrogenases. Furthermore, it p rovides an opportunity of applying the proven technique of water elect rolysis to a biological process.
