环保车辆中存在的氢燃料电池可以可能用作替代燃料来源。实际上很难大规模构建,因为它必须具有成本效益和更高效。
Researchers from the University of Central Florida (USF) may possibly have identified a solution for this.
Catalysts that are made using platinum are utilized for most of the hydrogen fuel cells. Most of the elements cannot tolerate the highly acidic solvents of the fuel cells present in the reaction, wherein the chemical energy of hydrogen is converted into electrical power. Gold, iridium, palladium and platinum are the only four elements that are corrosion-resistant. Iridium and platinum cannot be used on a large scale, as it is rare and costly.
UCF的教授Sergey Stolbov和博士后研究助理MarisolAlcántaraOrtigoza专注于适当地使用钯和黄金进行反应。他们开发了一种类似三明治的结构,具有经济且易于获得的元素层以及钯,黄金和其他元素,以使其更有效。
金或白金形成三明治的顶层。下一层有助于提高能量转化率,但也可以保护催化剂免受酸性环境的影响。这两个层存在于三明治的最低切片上。另外,钨稳定催化剂。
由于这些结构的形成,能量以较高的速率转换。由于未利用稀有和昂贵的金属,因此成本也降低了。
斯托尔博夫要求进行实验来评估预测。他已经与美国能源部的团队合作,以确定结果的重复和大规模申请的可能性。
When these hydrogen fuel cells become practically available, then the ozone layer destruction can be avoided.
