Abstract
This paper is in support of our current effort in the development of an experimental hybrid (lithium- aluminum alloy/electrolyte/oxygen or air) fuel cell for the acquisition of the experimental data required to characterize its performance behavior. The literature-based assembled formulation provided in this paper can be used to predict the cell open-circuit electric potential, lithium amount in the cell anode alloy, and g-atom ratio of lithium to aluminum in the cell anode as a function of time at any cell discharge current level. The ohmic voltage losses can also be computed in the cell cathode, anode, and two electrolytes at a cell current level. The computed ohmic-voltage loss data in the various components of the cell (Figure 1 in Section 1), during its discharge; for example, at the geometric current density of 0.10 amp∙cmgeom−2 at the cell temperature of 405 °C is presented in the paper. The computed data are summarized as given below: 1. The predicted open-circuit cell voltage at 405 °C is 2.3241 volt. 2. At the geometric current density of 0.10 amp∙cmgeom−2, the ohmic voltage loss in the cell anode is relatively negligible. The ohmic voltage loss in the electrolyte-1, electrolyte-2, and cathode is 1.3620, 0.0048, and 0.0002 volt, respectively. The ohmic cell voltage loss in the electrolyte-1 of thickness 10μm is dominant. It is, therefore, suggested that the electrolyte-1 membrane thickness be less than 5μm to reduce the overall cell operational voltage loss at any discharge current level. 3. The predicted operational cell voltage, at the cell discharge current of 0.10 amp∙cmgeom−2 is about 0.9571 volt at the cell temperature of 405 °C.
