The Netherlands-based HyET BV (Hydrogen Efficiency Technologies), has achieved a milestone in electrochemical hydrogen compression, reaching for the first time a single-stage pressure increase of more than 400 bar. At one side of the membrane a hydrogen-containing molecule (e.g., Electrochemical hydrogen compression.

The LL motors use the same inverter as conventional electric propulsion drives and operate at lower DC link voltage, allowing for a smaller DC link capacitor and reduced switch ratings. This results in a more compact and low-cost power electronic converter at the required power ratings used in commercial propulsion units.

They found that ionic hydrogen is evolved on the surface of the AC throughout the interior of the macro-scale electrode and nanoscale AC particle interior which, when the electrode potential is increased during cell discharge, is oxidized which causes a “pseudo-capacitive” effect, Seymour said. While emerging new converters.
