The planar solid-oxide fuel cells (PSOFCs) have emerged as one of the promising candidates for future energy system because of their high energy efficiency, fuel flexibility, zero emission, modularity and high tolerance to the fuel impurities.However, for large-scale commercialization of the PSOFC technology, there is a strong need of developing a reliable and highly efficient PSOFC power system. Development of such a reliable PSOFC based power system requires knowledge of the several feedback effects from the power electronics system and the application loads that may impact the PSOFC stack and the system as a whole. Therefore, it is important to develop analytical methodologies to investigate and mitigate the effects of these electrical feedbacks on the performance of PSOFC systems.On the whole, the dissertation focuses on i) the modeling and development of an effective PSOFC power-system design and system interaction analyses, ii) cost-constrained PES topology design for PSOFCS and iii) the design of cost effective optimal controller and controlling strategy for mitigation of electrical impacts with higher system efficiency.

High Quality Content by WIKIPEDIA articles! Vehicles and other mobile machinery used for transport (over land, sea, air, rail) and for other uses (agricultural, mobile power generation, etc) contribute heavily to climate change and pollution, so zero emission engines are an area of active research. These technologies almost in all cases include an electric engine powered by an energy source compact enough to be installed in the vehicle. These sources include hydrogen fuel cells, batteries, supercapacitors, and flywheel energy storage devices. In some cases, such as compressed air engines, the engine may be mechanical rather than electrical. This mechanical engine is then powered by a passive energy source like compressed air, or a combustible non-polluting gas like hydrogen. The above engines can be used in all vehicles, from cars to boats to propeller airplanes. For boats, energy sources such as nuclear power and solar panels can also be a viable option, in addition to traditional sails and turbosails.

Proton exchange membrane fuel cell (PEMFC), as a source of electrical power, provides numerous benefits such as zero carbon emission and high reliability as compared to wind and solar energy. The first part of this book attempt to model the voltage of PEMFC using simple and effective semi-empirical equations. The initial feature of the proposed technique is to incorporate the features of the mechanistic model with less complex equations. The second part of the book focuses on modelling the PEMFC temperature. The fault diagnosis procedure has also been elaborated for flooding and drying faults of PEMFC. Moreover, the electrical equivalent modelling has also been discussed all of the above-mentioned models consider ambient conditions changes directly.
