Title:
LIQUID HYDROGEN VAPORIZER, AND GENERATION METHOD FOR GENERATING HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2023/047937
Kind Code:
A1
Abstract:
A liquid hydrogen vaporizer generates hydrogen in a gaseous state or a supercritical state from liquid hydrogen. The liquid hydrogen vaporizer is provided with: an auxiliary heat exchanger for heating liquid hydrogen by means of the heat exchange with a heated fluid having a lower freezing point than the freezing point of sea water or industrial water; and an open-rack-type main heat exchanger equipped with a heat transfer tube through which hydrogen flows and a trough through which sea water or industrial water is flown down onto the outer surface of the heat transfer tube. The main heat exchanger heats hydrogen flowing out from the auxiliary heat exchanger by means of the heat exchange with sea water or industrial water.
