Hydrogen compressor

A hydrogen compressor is a machine that squeezes hydrogen gas so that it takes up less space. It works kind of like a bike pump, where you squeeze and push on the pump to make the air come out in a smaller space. The compressor is connected to a tank so that when the hydrogen is squeezed, it goes into the tank instead of coming out of the compressor. This helps store the hydrogen so it can be used later, like when you want to fill up your car with hydrogen.
