| 摘 要： | 为了制备一种骨架稳定的有机镁燃料电池多孔镁电极,通过扫描电镜、能谱分析及电化学方法研究了在1mol/L EtMgBr/THF的电解质溶液中,镁在金属镍和铜2种基体上沉积的电化学行为。结果表明：镁在2种金属基体上均可以发生沉积,而且在铜基体上还能够形成一层连续的镀层。采用在预镀铜的泡沫镍基体上电沉积镁的方法制备了一种新型骨架稳定的多孔镁电极,这种多孔镁电极的放电性能优于平板状的镁电极。

| Abstract: | In order to obtain a porous Mg electrode with a stable skeleton, organic Mg fuel cell (OMFC), the electrochemical behavior of Mg deposition on Cu and Ni metallic substrates in 1 mol/L EtMgBr/THF solution was investigated by SEM, EDS and electrochemical methods. The experimental results show that Mg can be electrodeposited on both substrates, as a continuous layer on a Cu substrate. Accordingly, an approach for producing a porous Mg electrode with a stable skeleton of OMFC was proposed by means of electrodep... |
