Description

Device for improving hydrogen utilization rate

Technical Field

Background

The existing hydrogen station gas source is transported into the hydrogen station by a 20MPa long pipe trailer, pressurized by a 45MPa hydrogen compressor and stored in a plurality of 45MPa hydrogen storage containers.
