3D printing for the fuel cell

Technology group AVL List relies on components printed with Inconel from M&H for the feed and drain lines to the fuel cell.

Without combustion at all, fuel cells generate heat and electricity from environmentally friendly hydrogen. They achieve high efficiencies in the process. In this process, the feed and discharge lines to the stack, i.e. the stack of the fuel cell, are exposed to high operating temperatures. In particular, the solid oxide fuel cell (SOFC), a special high-temperature fuel cell, heats the supply and discharge lines up to 800 degrees Celsius. This makes the use of high-temperature materials inevitable.

The Graz-based technology group AVL List therefore relies on know-how from M&H in this context. The Styrian 3D printing pioneer uses Inconel Alloy 625 for such requirements. “This is a nickel-based superalloy that has high strength properties and resistance to elevated temperatures. It also shows remarkable protection against corrosion and oxidation,” explains M&H Managing Director Patrick Herzig.
