Presenter: Ren\u00e9 Lorenz Abstract<\/strong><\/p>\n\n\n\n Aiming at a simple and computationally inexpensive method for analyzing a single cell setup in terms of (pumping power corrected) net power, a combination of analytical models are evaluated. Regarding the fluid flow, simplification assumptions allow for relating the pressure drop to the applied flowrate with a single explicit equation, which is implemented for three configurations: Flow Through electrode, Serpentine Flow Field and Interdigitated Flow Field. Multiplying \u0394p with flow rate Q gives the minimum parasitic pumping loss. A first estimation of the power output is obtained by applying a Thin Film Electrode model, coupled with fluid flow by assuming a flow factor that relates stoichiometric flow rate to applied flow rate. In a second step, a differential expression of the overpotential across the electrode thickness, solved numerically, accounts for the 3D porous reaction volume. The results are compared to numerical and experimental studies. <\/p>\n\n\n\n Full list of posters<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
