Clean hydrogen produced using hydrogen-permeable metal membranes was used in "fuel cells".
Here, we will explain other uses for hydrogen. Although it may not be widely known, hydrogen is used in a variety of fields. Please refer to the figure below.
① It plays an important role in nickel-metal hydride batteries, which can be reused after charging.
② It is used in the manufacture of semiconductors, which are essential components in mobile phones and computers that we use every day.
③ Liquid hydrogen is used as fuel for rocket engines.
④ Hydrogen is a good heat conductor, making it ideal for cooling. For this reason, it is used to cool generators.
In addition to the examples listed here, it is used in various other fields.
