【2015中石油职称英语阅读题:Hydrogen（Cars原文及答案文）】在近年来的科技发展过程中，新能源汽车逐渐成为关注的焦点。其中，氢燃料电池汽车因其环保、高效的特点，受到越来越多的关注。本文将围绕“Hydrogen Cars”这一主题，提供一份适合中石油职称英语考试的阅读理解材料，并附上详细的解析。
原文：
Hydrogen cars are a type of vehicle that uses hydrogen gas as fuel to generate electricity, which powers the car’s motor. Unlike traditional gasoline-powered vehicles, hydrogen cars produce only water vapor and heat as byproducts, making them a clean and environmentally friendly alternative.
The process of generating power in a hydrogen car involves a chemical reaction between hydrogen and oxygen in a fuel cell. This reaction produces electricity, which is then used to drive the electric motor. The main advantage of this technology is its high efficiency and low emissions. Additionally, hydrogen can be produced from various sources, including renewable energy such as wind and solar power, which further enhances its sustainability.
However, there are still challenges to the widespread adoption of hydrogen cars. One major issue is the lack of refueling infrastructure. Unlike gasoline stations, which are widely available, hydrogen refueling stations are limited in number and often located in specific regions. Another challenge is the cost of producing and storing hydrogen. Although the technology is promising, it is currently more expensive than traditional fuels.
Despite these obstacles, many countries and companies are investing heavily in hydrogen technology. Governments are offering incentives to promote the development of hydrogen vehicles, while automakers are working on improving the performance and affordability of these cars. As research continues and infrastructure improves, hydrogen cars may become a viable option for the future of transportation.
