Title: SYSTEM FOR TESTING HIGH-TEMPERATURE FUEL CELLS OPERATING WITH MULTIPLE FUELS, WITH DIRECT USE OF CARBON FUELS, WITHOUT CAUSING CARBON DEPOSITS IN FUEL DUCTS
Abstract:
The present invention relates to a system for testing high-temperature fuel cells operating with multiple fuels, with direct use of carbon fuels, including anhydrous carbon fuels, limiting or without causing carbon deposits in gas inlet and outlet ducts and in the anode flow channels, the system comprising: a furnace (5) containing a reactor (4), the reactor consisting of at least two interconnecting plates and at least one fuel cell (15) located between the two interconnecting plates, wherein one of the interconnecting plates in contact with a fuel cell is a cathode which receives oxidising gas and the other interconnecting plate in contact with the fuel cell is an anode which receives fuel gas. The system further comprises a means for supplying and discharging gases in a controlled manner, connected to the reactor (4), each plate further comprises a plurality of flow channels (14) in the top and bottom surfaces thereof, in which the oxidising gas and the fuel gas flow through the flow channels (14) before contacting the electrodes of the fuel cell (15), and the bottom, top and interconnecting plates are made of a zirconium oxide-based or cerium oxide-based material doped with one or more of the following oxides: yttria, scandia, calcia, gadolinia, samaria, alumina and cobaltite, the total quantity of dopants amounting to up to 20% by weight.
