Modeling and Optimization of Renewable and Hybrid Fuel Cell Systems for Space Power and Propulsion.

摘要

The project proposed to carry out two studies aimed at modeling and optimizing hydrogen fuel cells systems: i) the optimization of fuel cell structure for maximum power density, and ii) regenerative fuel cell systems. We believe the two areas are of great relevance to AFOSR's mission. For that the project achieved: the optimization of SOFC and PEMFC internal structure and external shape under a volume constraint; an initial set of subcomponent models for regenerative, renewable fuel cell system (RFC); the integration of PEMFC into RFC systems were developed; power electronic component models, and energy storage models were developed and implemented; pilot synthesis of renewable fuel cell system computational model with initial parametric studies regarding performance and reliability trends were implemented through the construction of a self-sustainable cabinet based on fuel cell technology and solar energy.
