Hydrogen diaphragm compressor is a special type of volumetric compressor with a structure that does not require lubrication.

Hydraulic hydrogen compressor is a popular choice in hydrogen applications due to its significant displacement advantage over diaphragm compressors.

To address the issues of mechanical wear and significant thermal losses at low power inherent in traditional mechanical compressors, the ionic liquid compressor was developed. This type of compressor works by replacing traditional pistons or diaphragms with a special ionic liquid that compresses the gas.
