Cars powered by fuel cells are also electric, though they use tanks of hydrogen to generate electricity and power an electric motor instead of banks of batteries. You can read more about them in our separate article on fuel cell cars.
How are these formed and how do they work ? Explain in detail when a metal reacts with an acid, hydrogen gas is usually produced. Explain the process of synthesizing copper(II) hydroxide from the solution of sodium hydroxide. Explain what is a fossil fuel and its formation? Explain the ...
Explain in a mechanistic manner how a deficiency in peptidyl transferase affects translation. Explain how pesticides kill and deter organisms, how they can move around in the environment, how they are studied (or not studied), why people use them (or don't use them), how they're ...
Graphenes, potentially, could help to make fuel-cell cars running on hydrogen a more viable prospect. [14]On the other hand, if you pepper tiny holes into graphene to make it porous, you get make a meshlike material called holey graphene that can work like an electrical semiconductor or a...
How lithium-ion batteries workLike any other battery, a rechargeable lithium-ion battery is made of one or more power-generating compartments called cells. Each cell has essentially three components: a positive electrode (connected to the battery's positive or + terminal), a negative electrode (...
