Electrochemical hydrogen compressor

An electrochemical hydrogen compressor is a machine that uses electricity to compress hydrogen gas. It's like a bicycle pump, but instead of pushing air into a tire, it compresses hydrogen gas into a container.

Imagine you have a balloon that you want to blow up. If you blow into it with your mouth, you're adding air and squeezing it in. That's how a regular compressor works. But if you want to compress hydrogen gas, you can use electricity instead, which is what happens in an electrochemical hydrogen compressor.

The machine has two parts: an anode and a cathode, which are separated by a membrane. The anode and cathode are like two sides of a battery, and when you pass an electric current through them, hydrogen gas molecules on one side are stripped of their electrons and become positively charged ions. On the other side, a chemical reaction occurs that accepts these positively charged ions and combines them with electrons to form hydrogen gas.

As more and more hydrogen gas is produced, the pressure inside the container increases, and it becomes compressed. This compressed hydrogen gas can then be used to power things like fuel cells, cars or industrial machinery.
