US Researchers said Friday in Los Angeles that they have developed a new electrically-assisted microbial fuel cell that does not require oxygen, enabling bacteria to produce four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.
This process is not limited to using only carbohydrate-based biomass for hydrogen production like conventional fermentation processes. Theoretically, it yields hydrogen from any biodegradable, dissolved, organic matter and cleans the waste water,according to Bruce Logan, a professor at Pennsylvania State University who led the study.
