Abstract: This paper constructed a new type of battery structure:magnesium anode chemical fuel cells in the marine sediments (MACFCS). The battery power output, polarization properties of cathode and anode and discharge characteristics are also investigated. The resutts showed that the MACFCS could obtain a stable performance for a long time under the condition of the external load.
