位于加利福尼亚州奥克兰（Oakland, California）的AC公交系统（AC Transit）增添了12辆氢燃料电池公共汽车，而且最近修建了两个氢燃料加油站，满足公交车队的需要。

请听人们对这些公交车的评论：

燃料电池利用电化学反应提供电能。公交车上的燃料电池利用氢氧产生电能，而且是零排放。

AC公交系统主管丹尼斯·巴特勒（Dennis Butler）说，他的公司同奥克兰官员一起提供环保型交通工具。他说：“我们认为，保护我们的星球是我们工作的一个重要部分。我们所服务的群众很关心环境可持续性。”

除奥克兰之外，美国还有其他11个地区也使用氢燃料电池公交车。2015年7月，夏威夷（Hawaii）宣布，计划在檀香山国际机场（Honolulu International Airport）采用氢燃料电池旅客班车。美国能源部（U.S. Department of Energy ）认识到这种清洁能源的使用潜力，正在研究开发各种途径，以便更好地生产、储存及输送氢气，降低成本，提高普及性。

Buses contribute to urban smog, but thanks to new technology they also might be the perfect vehicles to reduce air pollution.

Based in Oakland, California, AC Transit has added 12 hydrogen fuel-cell buses to its fleet and recently built two hydrogen fueling stations to accommodate them.

Just listen to what people are saying about the buses:

Fuel cells use electrochemical reactions to produce electricity. The cells in these buses  combine hydrogen and oxygen to produce energy with zero emissions.

AC Transit executive Dennis Butler said his company works with Oakland officials to provide the environment-friendly transportation. “We consider stewardship of the planet to be an important part of what we do,” he said. “The people we serve are interested in environmental sustainability.”

In addition to Oakland, 11 other jurisdictions in America use hydrogen fuel-cell buses. In July 2015, authorities in Hawaii announced plans for hydrogen fuel-cell buses to shuttle passengers around Honolulu International Airport. Anticipating greater acceptance of this green technology, the U.S. Department of Energy is researching ways to better produce, store and deliver hydrogen to lower its cost and increase its availability.
