Title
(EN) HYDROGEN FUSIBLE LINK
(FR) MAILLON FUSIBLE À HYDROGÈNE
Abstract
(EN) A hydrogen fusible link may include a first link member having a thermally conductive material, and reaction region and a bonding region. A bonding material may be in a solid state at an operating temperature and may have a melting temperature that is greater than the operating temperature. A catalyst material may coat the reaction region and may facilitate an exothermic chemical reaction when exposed to gaseous hydrogen to produce heat, wherein heat produced by the catalyst material is conducted to the bonding region via the body to heat up the bonding material. When the catalyst material is exposed to a concentration of gaseous hydrogen that is at or above an activation concentration the reaction region produces sufficient heat to raise at least some of the bonding material above the melting temperature thereby failing at least some of the bonding material.
(FR) Un maillon fusible à hydrogène peut comprendre un premier élément de maillon comportant une matière thermiquement conductrice et une zone de réaction ainsi qu'une zone de liaison. Une matière de liaison peut être à l'état solide à une température d'exploitation et avoir une température de fusion supérieure à la température d'exploitation. Une matière de catalyse peut revêtir la zone de réaction et faciliter une réaction chimique exothermique lorsqu'elle est exposée à de l'hydrogène gazeux pour produire de la chaleur, la chaleur produite par la matière de catalyse étant conduite jusqu'à la zone de liaison par l'intermédiaire du corps pour chauffer la matière de liaison. Lorsque la matière de catalyse est exposé à une concentration d'hydrogène gazeux supérieure ou égale à une concentration d'activation, la zone de réaction produit suffisamment de chaleur pour élever au moins une partie de la matière de liaison au-dessus de la température de fusion, ce qui fait fondre au moins une partie de la matière de liaison.
