National regulations are about to enter effect in China with the aim of promoting the standardised and high-quality development of the hydrogen-bicycle industry. One way or the other, it’s the future of personal urban transport. Time to get up to speed.
国家法规即将生效，旨在推动氢能自行车产业规范化、高质量发展。无论如何，这都是个人城市交通的未来。是时候跟上进度了。
The “General Technical Requirements for Hydrogen-Assisted Bicycles” is to be officially implemented on 22 October. Behind it is the industry leader in China, Youon, with the participation of 11 hydrogen-energy research and production companies, as well as testing and certification bodies.
《氢能自行车通用技术要求》将于10月22日正式实施。其背后是中国的行业领军企业永安集团，以及11家氢能研究和生产公司以及检测和认证机构的参与。
The standards stipulate the overall requirements for hydrogen-assisted bicycles and technical requirements for their fuel cell systems, hydrogen storage devices, test methods, etc., as the Yangtze Evening News reported yesterday, 9 October.
据扬子晚报昨日10月9日报道，该标准规定了氢助力自行车的总体要求，以及燃料电池系统、储氢装置、试验方法等技术要求。
At the same time, a unified-standard system has been established as regards product quality and performance, which is hoped to be instrumental in improving industry competitiveness and sustainable development. The standards are without doubt a significant step toward China achieving its carbon-neutrality goals.
同时，在产品质量和性能方面建立了统一的标准体系，有望有助于提高行业竞争力和可持续发展。这些标准无疑是中国实现碳中和目标的重要一步。
But before rushing out to buy one (and they are on sale now, as this publication reported a year ago), better to be familiar with using the new revolution in personal transportation.
但在急于购买之前（正如本出版物一年前报道的那样，它们现在正在促销），最好先熟悉如何使用个人交通工具的新革命。
First up, hydrogen-powered bikes are a dream compared to e-bikes. That 10 hour charge time? Forget it. A hydrogen-powered bike takes 10 seconds.
首先，与电动自行车相比，氢动力自行车是一个梦想。充电时间10小时？忘了它。氢动力自行车只需 10 秒。
Youon is the first mass-produced consumer-oriented hydrogen bicycle in China, and it’s based in Changzhou of our very own Jiangsu Province.
永安是中国第一款量产的消费级氢能自行车，总部位于江苏常州。
As to its use, a home hydrogen generator, provided by the manufacturer, fills a cylindrical tank, about as long as your forearm. Plop it in the bike and you’re ready to go. For the technically minded, the generator relies on proton-exchange-membrane (PEM) electrolysis to realise the hydrogen.
至于其用途，制造商提供的家用氢气发生器可填充一个圆柱形储罐，大约与您的前臂一样长。把它放在自行车上，你就可以出发了。对于有技术头脑的人来说，该发生器依靠质子交换膜（PEM）电解来产生氢气。
And when we come to actually riding the bike, that’s where it gets interesting. In the case of a Youon bike, there are three gears. In first gear, you’re on your own; pedal power all the way. Burn some calories.
当我们真正骑自行车时，这就是有趣的地方。就 Youon 自行车而言，有三个档位。在第一档，你只能靠自己；全程踏板动力。燃烧一些卡路里。
Second and third gears are hydrogen-assist modes, demarcated by power. In both gears, acceleration and deceleration are controlled by the pedals. Third gear will realise a top speed of 22 km/h.
二档和三档为氢气辅助模式，以功率划分。在这两个档位中，加速和减速均由踏板控制。三档最高时速可达22公里/小时。
While there are so many upsides to hydrogen power, many have their concerns, not least the fact that hydrogen is an extremely dangerous, flammable and explosive gas.
尽管氢能有很多优点，但许多人也有自己的担忧，尤其是氢是一种极其危险、易燃易爆的气体。
Yet, the quantity of hydrogen required for a bike is not particularly large, while its tank is also different from traditional large-scale hydrogen storage in so far as it relies on lanthanum pentanickel (LaNi5), a rare-earth-element based compound with hydrogen storage capacity.
不过，自行车所需的氢气量并不是特别多，而且其储罐也与传统的大规模储氢不同，它采用的是具有储氢能力的稀土元素五镍镧（LaNi5）。
That hydrogen is also released incredibly slowly, so much so it is said to be nigh-on impossible for it to reach a concentration level in air of 4 percent, the minimum needed for hydrogen to combust.
氢气的释放速度也极其缓慢，以至于据说它在空气中几乎不可能达到 4% 的浓度水平，这是氢气燃烧所需的最低浓度。
The periodic table therefore looks as if it shall be instrumental in bringing down emissions, with its most basic element of all playing the leading role in the development of future transportation. And the byproduct of it all? Water.
因此，元素周期表似乎有助于减少排放，其最基本的元素在未来交通的发展中发挥着主导作用。而这一切的副产品呢？水。
