A hydrogen getter is a material that absorbs hydrogen gas to maintain a vacuum or a controlled atmosphere in a sealed system. These getters are crucial in applications like cryogenic storage, transport, where the presence of hydrogen can cause corrosion or device failure. Absorption: Hydrogen getters actively absorb hydrogen gas, removing it from the surrounding environment. Cryogenics: Incorporated into containers and pipes for liquid gases like LNG and LH2 to maintain a high vacuum and prevent degradation. Molecular sieves: Materials like silver molecular sieves are used in high-vacuum applications to absorb hydrogen released from materials like steel. Ag-Zeolite Hydrogen Getter Silver molecular sieve is a new generation of high-efficiency hydrogen absorbing material used in the vacuum interlayer of high-vacuum multi-layer insulation containers.
