British researchers at the national meeting of the American Chemical Society today announced a new kind of “biofuel cell” that produces electricity from ordinary air mixed with small amounts of hydrogen. Because the new cell uses bacterial enzymes rather than platinum as a catalyst, it offers a much less expensive path to the much-hyped hydrogen […]
Using a new electrically-assisted microbial fuel cell (MFC) that does not require oxygen, researchers have developed the a process that enables bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone. Dr. Bruce Logan, the Penn State professor of engineering and co-inventor of the MFC, […]
