It's important to note that in hydrogen-powered vehicles, the hydrogen isn't used for combustion. How does hydrogen work in a car then? From its tank, the hydrogen is passed through an anode in a fuel-cell. The anode has a catalyst – usually platinum – which forces the hydrogen to...
While hydrogen is abundant, it is often found attached to other elements and needs to be separated out to be used as a fuel. Depending on the method used, this process can be very carbon intensive, and while sustainable options exist, they require further development. ...

How does a hydrogen fuel cell work? In simple terms, a hydrogen fuel cell is made up of a positively charged anode and a negatively charged cathode that are put in contact with an electrolyte. A platinum catalyst then kick-starts a chemical reaction that generates electricity, heat and water...
What does a hydrogen ion look like? What is the mass number of hydrogen? What is the valency of hydrogen? What is the elementary charge of an electron? Why do hydrogen ions have a positive charge? What is the electronegativity of hydrogen?
根据句子结构可知,power plant就是指 的后面的 fuel cell(燃料电池),还有下段中句子A fuel cell, very simply described, is a power generator, making electricity through the combination of hydrogen and oxygen.故 据此推断答案选A,一个发电装置。 3.C 细节理解题。 根据第三段中句子:Fuel cells generate...
How Does a Hydrogen Fuel Cell Bus Work? A hydrogen fuel cell bus has three main components: the fuel cell stack, the electric motor, and the hydrogen storage tanks. The fuel cell stack is made up of individual fuel cells that combine hydrogen and oxygen to produce electricity, heat, and ...
This thesis reports on two technology and policy issues directly related to hydrogen economy. The first issue concentrates on the end-use application of hydrogen as a transportation fuel, and deals with the following question: what is the place of hydrogen fuel cell vehicles among the new, more...
A. High speed and low cost. B. Zero emissions, long driving range, and quick refueling. C. Large size and strong power. D. Beautiful appearance and comfortable seats. 相关知识点: 试题来源: 解析 B。中文解析:文章中明确提到氢燃料电池汽车具有零排放、行驶里程长和加油快等优点。A 选项文中未提...
