Construction and Performance Research of Magnesium Anode Chemical Fuel Cell in the Marine Sediment Layer

摘要: 研究了一种新型电池结构:海底沉积层镁阳极燃料电池。测试了镁阳极在海底沉积物层的应用性能,研究了组装电池的功率输出,阴、阳极极化性能及长期放电特征。结果表明,电池开路电压1.947 V,电池最大功率密度44.33 mW/cm²,自腐蚀速率(放电电流密度)0.009 mA/cm²,电流密度较大,电位较负,在外接负载条件下长期工作性能稳定。

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.
