No additional layers were applied between electrodes and current collecting meshes. The mechanical load on the meshes was always 20 MPa or higher (kgf per area of current collecting mesh). All current leads and potential wires are made from Pt-wire. Sealing of the single cells was done using either gold or a glass-ceramic seal. The thermocouple, used to measure and taken as the operating temperature of the cell is located in the cell housing itself, closer than 10 mm from the cell. 5 l/min argon.

It is also shown i n Figure 5 that increasing hydrogen flow rate gives higher OCV readings. However, the slope of OCV increasing after 100 mllmin reduces compare to the initial increase of hydrogen flow rate from 20 to 100 mLimin.

With increasing gas flow- the effective anode temperature increases. The increased cell temperature will also cause an enhanced catalytic activity as well as lower polarization resistance of the anode. 42 9 Advances in Solid Oxide Fuel Cells I1 Influence of Anode Thickness on Electrochemical Performance 80 t.. , I.....
