FIELD: electrical engineering. SUBSTANCE: fuel element with solid electrolyte relates to electrochemical sources, specifically to high-temperature fuel elements with solid oxide electrolyte. Current tap of fuel element with solid electrolyte is manufactured from metal alloy containing chrome, iron and rare-earth elements. Alloy additionally includes rhenium or at least one of elements of group of platinum metals and is characterized by following proportion of components, per cent by mass: chrome 25.0-30.0; rare-earth element 0.1-2.0; rhenium or one of elements of group of platinum metals 2.0-4.0; iron being the balance. EFFECT: maximum approximation of coefficient of thermal expansion of metal scale-resistant alloy for manufacture of current tap to coefficient of thermal expansion of solid electrolyte within temperature interval 25-1000 C, decreased contact resistance on boundary current tap/electrode. |
