PROBLEM TO BE SOLVED: To provide a method for executing a stable methane fermentation process without causing accumulation of hydrogen or souring by providing a hybrid system composed by combining a methane fermentation process of organic matter with a microbial fuel cell, in a methane fermentation process of organic matter. SOLUTION: In the microbial fuel cell, a negative electrode is inserted into a culture medium of an anaerobic fermenter for executing the methane fermentation process therein; the negative electrode is a fibrous graphite electrode; and the pH of the fermenter is 6-8. The methane fermentation process of organic matter can be executed in the anaerobic fermenter by using the microbial fuel cell. COPYRIGHT: (C)2007,JPO&INPIT
