Abstract

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.
