In Germany, researchers at Ruhr-University Bochum, University of Utah and the Max Planck Institute for Chemical Energy Conversion developed new techniques with which bacterial enzymes can be efficiently coupled to electrodes and designed a hydrogen-oxygen biofuel cell based on a hydrogenase enzyme. They also implemented a system for ammonia synthesis based on a nitrogenase enzyme. […]

European researchers find way to make hydrogenase fuel cells viable

November 14, 2018 |

In Germany, fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction – hydrogen – to reach the enzyme-loaded electrode. Researchers […]
