Different energy sources and converters need to be integrated with each other for extended usage of alternative energy, in order to meet sustained load demands during various weather conditions. The objective of this paper is to associate photovoltaic generators, fuel cells, and electrolysers. Here, to sustain the power demand and solve the energy storage problem, electrical energy can be.
From a technical perspective, dynamic operation has a significant effect on the fuel cell life cycle and, hence, economic viability of the device. The scope of this thesis is to present an improved understanding of the system behaviour at transient operation that can be used to design a more robust control system in order to overcome the cost and the operating lifetime issues.
We present a dynamic and spatially distributed mathematical model of a molten carbonate fuel cell (MCFC) that is installed onboard an existing merchant vessel. Using measured operational data, the model has been calibrated and validated both for steady state and transient operation.
Modeling and simulation of JP-8 fuel based hybrid solid oxide fuel cell system Kalyan Nishtala. this technology, this work develops dynamic, computer-based, mathematical models of an Auto-thermal reformer (ATR) based SOFC system with Jet Propellant-8 as the fuel to the ATR.
In this paper, we develop two computational models for the electrical performance of the tubular solid oxide fuel cell designed by Siemens Westinghouse Corporation. The first model makes simplifying assumptions for activation and concentration polarizations and obtains an analytical solution.

A SYSTEM DYNAMICS MODELING METHODOLOGY FOR COMPRESSIBLE FLUID FLOW SYSTEMS WITH APPLICATIONS TO INTERNAL COMBUSTION ENGINES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Kenneth Michael Follen, M.S.
The thesis consists of seven chapters. The first chapter includes the general contemplation of fuel cell, specifically for the SOFCs. It presents the history of the solid oxide fuel cells and the use of them nowadays. At the end of the chapter the factors of the efficiency of the cell and the different kinds of losses are presented.
