| 摘要 |
The present invention relates to a method for producing electrical energy or hydrogen gas from a gas stream containing one or more gaseous compounds that are oxidatively degradable by microbes, the method comprising contacting the gas stream with an anode of a bioelectrochemical device, said anode containing said microbes which oxidatively degrade one or more of said gaseous compounds while producing electrical energy or hydrogen gas by said oxidative degradation, wherein: (i) said anode is sufficiently porous such that gas is permitted to flow therethrough, (ii) said anode contains on its surface and/or interior portions a proton-conducting medium, and (iii) said anode is in electrical communication with a cathode of the bioelectrochemical device. The invention is also directed to a bioelectrochemical device (e.g., microbial fuel cell) configured to accomplish the above method.
