1997), but the electrodes under investigation appeared not to be polarized; the short explanation is that the reference electrodes were not working. The geometric requirements for the position of electrodes in three-electrode set-ups have been treated in detail by several researchers (Nagata et al. 1998; Reinhardt and Göpel 1998; Adler 2002; Mogensen 2002), and there is a general agreement among these researchers. In spite of this, there still seems to be a great need in the SOC community for basic information on how to measure electrode potentials properly; some of these details are given below.

No fuel is available, at which the fuel cell voltage becomes ‘zero’, too. e. fuel) and the desire to uphold the current flow and the further transport of oxygen ions through the electrolyte will lead to higher than desired oxygen partial pressures at the anode side. The obvious loss of fuel by retaining a nonzero flow of fuel out of the cell can be managed by recycling the anode off-gas to the anode inlet and thus reusing the excess fuel. Returning to Eq. (49) and using Eq. (44), though, at a given uF, the efficiency of the cell will only depend on the value of the actual cell voltage.
