Scientists at Oxford University have invented a bio enzyme fuel cell that can power electronic devices The cell consumes oxygen and hydrogen in the atmosphere The enzymes used are isolated from bacteria that metabolize hydrogen in nature The enzyme is characterized by high selectivity and can tolerate gases that are toxic to traditional fuel cell catalysts, such as carbon monoxide and hydrogen sulfide Because the enzyme can grow, it is a cheap and renewable cell compared to the expensive platinum catalyst used in other hydrogen fuel cells, the researchers said The fuel cell, designed by the team led by Professor Fraser Armstrong, consists of two electrodes coated with enzymes They are in glass tanks filled with normal air and a small amount of hydrogen Because of its selectivity and tolerance, the gas in the catalyst can be mixed without expensive fuel isolation membrane Armstrong said: the results of this study give fuel cells more application space, because cost has always been the main problem in fuel cell application, and it can not guarantee clean fuel sources and need instant power Translated by Zhang Liying: http://
