Description

technical field [0001] The present invention relates to the use of a marine yeast. It also relates to a microbial fuel cell obtained by utilizing the marine yeast and a preparation method of the cell. Background technique [0002] Microbial fuel cell is a device that converts chemical energy in organic matter into electrical energy through microbial catalytic reactions (Z.Du et al., 2007). To the cathode, it forms a loop with an external circuit to achieve electricity generation (R.M.Allen et al., 1993). The concept of microbial fuel cells was first proposed by Potter in 1910, and then he used platinum electrodes to realize the earliest MFC electricity generation in E. coli culture medium. Research in the 1980s found that after adding electron transfer intermediates to microbial fuel cells, the current density and output power were increased in a large range (F.Davis et al., 2007), which provided possible opportunities for practical applications (K. Rabaey et al., 2005). ...
