Abstract : This final report describes progress and accomplishments of the MIT MURI Microchemical Systems for Fuel Processing and Conversion to Electrical Power. The program aimed to develop a fundamental understanding of the different physical phenomena underlying fuel processing at millimeter to micron scale as well as to establish the engineering principles needed to realize portable electrical power generation from hydrocarbon fuels. Competing approaches to fuel conversions were addressed with particular emphasis on two basic strategies: (i) conversion of hydrocarbons to hydrogen by partial oxidation, reforming, and product separation steps; and (ii) direct conversion of hydrocarbon fuels in microfabricated solid oxide fuel (SOFC) cell systems. Advances have been made in design and microfabrication strategies for microchemical systems capable of operating at elevated temperatures and being rapidly cycled between low and high temperatures; microfabrication and characterization of SOFC electrolyte and electrode materials; synthesis of novel catalytic materials; understanding and engineering approaches to integration of materials with different thermophysical properties into systems undergoing large spatial and temporal temperature variations; and development of systems engineering concepts and tools for understanding and predicting the performance of integrated microchemical systems at steady state and during transients.
