Hydrogen energy and new energy
Focus on the safety control of high-pressure hydrogen (35/70MPa) and liquid hydrogen (-253℃). In hydrogen refueling stations, valves need to address sealing failure caused by "permeation embrittlement" of high-pressure hydrogen; in liquid hydrogen storage and transportation, special low-temperature materials need to be used to prevent cold brittleness; in PEM electrolyzers, they need to withstand high-potential oxidative corrosion.
