The ionic compressor
In five steps, the ionic compressor condenses gaseous hydrogen to 100 MPa. Highlights include the eponymous ionic liquid, which does not bond with the gas. It acts as both a lubricant and coolant, and thus significantly reduces wear and tear. Additionally, the ionic compressor has fewer moving parts than a typical piston compressor. The liquid also increases the compressor’s energy efficiency due to better cooling and fewer dead spots during the compression process.
By eliminating the need for lubricants, the ionic compressor protects the hydrogen against the risk of contamination. This ensures high levels of purity, making the compressor ideal, for example, for purity-critical fuel-cell applications.
