Analytical Modelling of Fuel Cells Excerpt :

In fuel cell research, the gap between fundamental electrochemical processes and the engineering of fuel cell systems is bridged by the physical modelling of fuel cells. This relatively new discipline aims to understand the basic transport and kinetic phenomena in a real cell and stack environment, paving the way for improved design and performance. The author brings his unique approach to the analytical modeling of fuel cells to this essential reference for energy technologists. Covers recent advances and analytical solutions to a range of problems faced by energy technologists, from catalyst layer performance to thermal stability Provides detailed graphs, charts and other tools (glossary, index) to maximize R&D output while minimizing costs and time spent on dead-end research Presents Kulikovsky’s signature approach (and the data to support it)—which uses "simplified" models based on idealized systems, basic geometries, and minimal assumptions—enabling qualitative understanding of the causes and effects of phenomena

Transient Numerical Modeling of Proton exchange membrane Fuel Cells Excerpt :

Hydrogen fuel cells convert the chemical energy of hydrogen directly into electricity, with the only byproducts being heat and water. The high cost of hydrogen fuel cells due to the expensive platinum catalyst is one of the limiting factors to their global commercialization. Improving fuel-cell performance while reducing the required amount of the catalyst can be achieved by optimizing the water balance in the cell that aims at striking a balance between electrolyte dry-out, which leads to high ohmic resistance, and liquid-water accumulation, which results in reactant starvation. Interpretation of the experimental measurements necessary for making design decisions is, however, often challenging due to the sub-millimeter scale of the fuel-cell components. Mathematical models have become a valuable instrument for gaining insight into the physical processes taking place in fuel cells. Because of the coupled electrochemical reactions, heat, mass, and charge transport that occur at multiple spatial and temporal scales, fuel-cell modeling is a complex task that is best addressed with the help of numerical simulations. As the common fuel-cell characterization experiments are dynamic in nature, their analysis requires transient models. In this thesis, an open-source transient numerical model of a hydrogen fuel cell is developed. The model is applied to interpret electrochemical impedance spectra of fuel cells, highlight the shortcomings of the analytical methods previously used for this purpose, and to better understand liquid-water dynamics in fuel cells. First, the transient model is used to analyze water-management signatures in fuel-cell impedance spectra under dry conditions. This work shows that the low-frequency inductive behavior observed experimentally in hydrogen fuel cells is influenced by the finite-rate water uptake by the electrolyte and water transport within the electrolyte, which impact the frequency and the size of the inductive loops in the spectra.
