氢车为啥只有一种储氢选择？-4G光元通信能源
4G光元：燃料电池已经成为汽车行业越来越受欢迎的驱动设备，燃料电池把氢气和空气中的氧气结合时，产生电力和水。氢气可以由天然气重整或电解水制成，然后压缩储存。挑战：如何在低压下储存氢气？
美国海军研究实验室替代能源负责人卡伦·斯维德·里昂博士将燃料电池应用于无人机。在本周的技术简报网络视频演示中，无人系统推进进展，读者问里昂：卡伦·斯维特里昂博士
碳纳米管储氢最近有什么新进展？卡伦·斯维德·里昂博士：如果你能想像如果你有一个压缩的氢气罐马克图姆王储 ，你就有了氢气，除此之外就是氢气罐，铝和碳纤维缠绕的; 如果您在低温下将碳氢化合物储存在碳纳米管上，则您就拥有非常轻便的金属储氢罐剑道真解，但您却经常需要携带加热器来加热。加热释放氢气到燃料电池中使金属储氢变得非常复杂。我们总还是要在燃料电池外保持20-30psi;您经常需要调整存储压载才能做到这一点。山田光子 我们试图用这些储存氢气的替代系统桃乐丝公牛血 ，但看到的是，它们的重量和复杂程度像滚雪球王智胸围 ，不断增长和迅速变大，我们最终只能回到压缩氢气。甚至低温储氢在纸上/文章中看起来都很棒暗宅之迷 。但是，当我们实际做到这一点，所有的好处开始在我们处理过程中逐渐消失，因为它的实现起来实在太复杂了。这就是为什么汽车行业只有压缩氢气一种选择的基本原因李馥莹 。也许你并不怎么看，你怎么看？在下面分享您的意见和问题。另：阅读更多推进技术简报。
Sound-Off: Can Hydrogen be Stored in Carbon Nanotubes?
The fuel cell, an increasingly popular device in the automotive sector金民灿 , creates a power source when coupled with hydrogen. The hydrogen can be made from natural gas or electrolysis of water and then compressed for storage. The challenge: How do you store hydrogen at low pressure张毅涵 ?
Dr. Karen Swider Lyons, Head of Alternative Energy in the U.S. Naval Research Laboratory,exe文件打不开 applied the fuel cell to unmanned air vehicles. During this week’s Tech Briefs webcast presentation,Advances in Unmanned System Propulsion, a reader asked Lyons:
Dr. Karen Swider Lyons
What are the latest advancements of hydrogen storage in carbon nanotubes?
Dr. Karen Swider Lyons:If you can imagine a compressed hydrogen tank, you have hydrogen, and then your other material is that hydrogen tank; you’ve got aluminum and carbon overwrapped fibers. If you had the hydrogen stored on carbon nanotubes at low temperatures, you have a very地藏心经 , very lightweight metal tank, but you often need to carry a heater to heat up the carbon. Then, it gets very complicated, modulating the hydrogen that is coming out of the alternative solid storage into the fuel cell.
We always have to keep 20-30 psi outside of the fuel cell; you often need ballast storage to do that. What we've seen with these alternative hydrogen systems is that their weight keeps growing and growing. They're so complex that we just end up going back to compressed hydrogen.
Even cryogenic hydrogen looked great on paper. Then, when we actually did it, all the benefits started to disappear before us as we worked with the system金蜘蛛轴承网 , because it got very complex to implement. That's the reason why the automotive industry is going 100 percent with compressed hydrogen.
