When long term electro-chemical tests (>1000 hours) are run to monitor the cell degradation at the cathode for example, it is important to avoid any contaminant in the gas flow rate.Inconel 601 flange equipped with alumina housing and alumina tube to feed the gas to the electrode during long term test (>1000 h)Typical poisoning is coming from the chromium contained in the steel tubing. The volatile chromium species (Cr6+) will flow into the cathode (with the air) and thanks to the intake of electrons at the electrode, the chromium ion will transform to chromium oxide and be deposited at the cathode triple point. In such a case, the long term test kit is used. The Inconel 601 flange is equipped with an alumina housing (>96 % Al2O3) and the air (or other gas) is led through an alumina tube. The long term test kit is fully compatible with other functionalities proposed with the Open Flanges™ test Set-Up as the integrated steamer or the small pellet test kit. The long term test kit can be implemented on the fuel, on the air or on both sides.

Flexible cell dimensions: cells of Ø 8 to Ø 80 mm (or square till 70x70 mm) can be successively installed Quick start of experiment: less than 20 minutes to remount a new cell with different dimension, thanks to the simple design without sealing Other SOFC components: the open flanges test rig is also useful for conductivity measurements (electrolyte, electrode material, interconnect etc.) and sealing tests End of broken cells and secure testing: the cell is squeezed by a soft alumina felt that prevents any damages, the excess fuel burns continuously in the alumina felt at the cell edges

The ceramic pellets that generally have a diameter between 6 to 12 mm and a thickness of 2 to 4 mm are blocked on a special flange with a disc of soft vermiculite (mica) that has the same high of the ceramic sample and prevents the latter (or the flanges) to toggle. Gold or other appropriate M_Grid™ materials are placed on both sides of the pellet for potential and current measurement. After this operation, the double ceramic felt caps are covering the sample as for any other cell mounting in the Open-Flanges™ test set-up.
