Elaboration and Electrochemical Characterizations of up-Scaled Protonic Ceramic Cells
In the frame of METPROCELL project supported by European Community’s 7thFramework Programme (FP7/2011-2014) for the Fuel Cells and Hydrogen Joint Technology Initiative and coordinated by TECNALIA (SP), up-scaled anode-supported cells (ASC) have been elaborated by wet chemical routes. ASC requires the use of tape-casting method in order to manufacture the support. Then, both electrolyte and cathode are screen-printed on the NiO-electrolyte substrate (cf. Figure 1).
Based on previous works [1-3], promising performances (170 mW/cm² at 0.7V, 600°C, cf. Figure 2) and long term testing (thousand hours) have been measured on middle-scaled protonic cells (20 cm²). Microstructure evidenced by SEM analysis and electrochemical performances (IV-curves, Impedance Spectroscopy measurement) as well as durability measurement will be presented and discussed.
