Modeling of Solid Oxide Fuel Cell and hydrogen storage using Metal Hydrides — •Zahra Harati1, Jan Lohbreier1, and Gholam Reza Nabi Bidhendi2 — 1Faculty of Applied Mathematics, Physics and Humanities, Technische Hochschule Nürnberg Georg Simon Ohm — 2University of Teheran
Multi-energy systems provide extensive benefits over conventional single-source power generation including enhanced efficiency, reduced greenhouse gas emissions, and extended reliability. In the considered multiple system, the solid oxide fuel cell has been selected that can flexibly utilize different fuels, including hydrocarbon gases, coal, and natural gas. In this study, pure hydrogen is produced by PEM electrolysis and stored in lithium borohydride used as fuel in SOFC. Using MATLAB/Simulink, we model the SOFC as a black box using a zero-dimensional approach. The model comprehensively accounts for all SOFC losses, including partial pressure, activation losses, concentration, ohmic losses, and exergy losses, allowing for a complete characterization of the system.
