HIGH-TEMPERATURE SOLID-ELECTROLYTE FUEL CELL Russian patent published in 2006 - IPC H01M8/10 H01M8/12 

FIELD: electrical engineering; high-temperature solid-electrolyte fuel cells.

SUBSTANCE: proposed high-temperature solid-electrolyte fuel cell has effectively functioning part-to-part metal interconnections made of iron and chromium alloy with cobalt and nickel newly introduced therein, proportion of ingredients being as follows, mass percent: chromium, 5 - 15; nickel, 30 - 45; cobalt, 20 - 35; iron, the rest; nickel and cobalt to chromium content ratio ranges between 4 and 13. Alloy may incorporate associated impurities, such as carbon, nitrogen, silicon, sulfur, phosphor, and copper whose total content is not over 1% which does not impair alloy quality.

EFFECT: enhanced service life and operating reliability of fuel cell.
