In an effort to reduce carbon emissions, airport staff is testing hydrogen powered bicycles to replace cars to get around the airport facility.
为了减少碳的排放，机场的工作人员正在测试，用氢动力自行车来代替汽车在机场里穿梭。
[Yuko Tsubone, Airport Employee]:
“Because (the airport) is really large, it makes it easier to get around. I also think it’s really nice since you can pedal without having to put in a lot of effort, and so you don’t get tired.”
[Yuko Tsubone, 机场员工]:
“因为（机场）实在是太大了，所以这样穿梭在机场里变得更轻松。我也认为这是非常好的，因为你可以踩踏板而不必耗费许多力气，所以你不会感觉到很累。”
The bicycle uses a hydrogen fuel cell to charge the onboard battery, similar to that used in an electric assisted bicycle. The system allows users to quickly fill up on hydrogen instead of waiting for a battery to charge.
自行车采用氢气燃料电池，来充车上电池的电，类似用在电动自行车上的电池。这种系统可让使用者快速填补氢气，而不用再等待电池充电。

7. oxygen ：n. 化学元素 — 氧
8. convert ：v. 转换
9. cartridge ：n. 在此为盛装氢气的器具
10. emit： v. 排放

12. carbon dioxide：n. 二氧化碳
The fuel cell generates electricity through an electrochemical reaction. Hydrogen is broken down and then combined with oxygen converting chemical energy into electrical energy.
燃料电池是经由电化学反应来产生电力。氢气先被分解，然后与氧气结合，这样的反应可使化学能转换为电能。
[Yusuke Nagai, Hydrogen Energy Dept., Iwatani Corp.]:
“The bicycle has a hydrogen cartridge and fuel cell inside. The hydrogen is sent to the fuel cell, and the electricity that is produced is then used to provide the power to assist pedaling.”
[Yusuke Nagai, 氢气能源部门, Iwatani 公司]:
自行车内部有着装载氢气的器具和燃料电池。氢气被传送到燃料电池里，并且产生电力，然后所产生的能量可协助骑自行车。
The main benefit of using hydrogen as the energy source for the bicycles is that it is 100 percent environmentally friendly. The only waste product is water which emits only steam rather than carbon dioxide.
使用氢气作为自行车动力的来源，主要的好处是，它是百分之百环保的。唯一会产生的废物是水，它排放的只有水蒸气，而不是二氧化碳。
