Zhongan Online and Zhongan News Client News were reported from China's University of Science and Technology on July 2 recently, Professor Gao Minrui of the University of Science and Technology of China and Professor Tang Kalawan prepared a bronze doped modified molybdenumnum-nickel-based alloy Catalyst, who has successfully resolved the Cathode Corrosion problem during the starting process of replacing the vanity.该催化剂显示出氢氧化物反应和惯性对碱血管中还原的反应的极大催化活性。这种独特的双功能特征可以有效抑制由于阶段开始时还原氧的反应引起的电势界面的即时界面,从而保护了阴极。 6月25日,相关结果发表在“德国应用Kimpel”中。作为一种干净有效的能源转化技术,氢燃料电池是大型应用中的主要瓶颈。其中,腐蚀在开始期间由电流衰减引起的阴极和戒烟是影响耐用性的一个主要问题。 It triggers a reaction of oxygen, resulting in a potential interface difference of more than 1.5V, resulting in severe oxidative damage to carbon carbon and catalyst Research team has prepared a modified copper binG molibdenum-nickel-based alloy catalysts by heating the microwave and subsequent heat treatment, and used it as anode catalyst for an anion exchange membrane fuel cell, and then conducted a simulated start-stop cycle test.结果表明,与商用铂碳阳极相比,使用该催化剂在电池工艺开始期间,潜在的阴极转移从1.4V显着降低到安全。经过10个起步周期后,阴极催化剂层的厚度几乎保持不变,并且阴极转移的阻抗越来越低于铂碳催化电极。峰值退休的退休率达到了61%,比铂碳催化剂和未含量的钼镍合金催化剂明显好,阴极腐蚀现象几乎消失了。 Pinakilresearchers说,这项工作已经开发出一种良好的非必需金属阳极催化剂,提供了一种简单有效的解决方案,可以在燃料电池的启动过程中解决关键的反向电流衰减问题,并且可以显着提高电池耐用性而无需复杂的系统变化。 (记者王Qiao)
