Methods and Tools for Designing Profitable Hybrid Systems
Roger A. Dougal, PhD, Professor of Electrical Engineering, VTB Project Director, University of South Carolina
Style of fuel cell and battery hybrid systems entails integration of strongly interdisciplinary sub-systems involving every little thing from electrochemistry and power electronics to fluid and heat transfer. The design procedure can be simplified by the application of proper multidisciplinary design and style tools. This presentation will describe methods for hybrid system design and illustrate those methods with instance systems that have been validated in hardware.
Direct Borohydride Fuel Cells: A Nzovel Class of Fuel Cell – Battery Hybrid Technologies
Gennadi Finkelshtain, Chief Technical Officer, Medis Technologies
Medis Technologies Direct Borohydride Fuel Cells (DBFC) gives a compelling option to the classic fuel cell chemistries. Medis has launched its first consumer product, the Medis 24/7 Power Pack, based on a novel approach, like proprietary chemistry and assembly technologies. We will provide an overview Energy Pack item, including functionality, production technologies and chemistry. Medis has created a second generation hybridized version of our Energy Pack and we will offer an overview of our hybridization method, like an overview of the performance advantages developed by hybridization.
Identification and Characterization of Near-Term Industrial Markets for PEM Fuel Cells in Portable Applications
Kathleen Judd, Senior Research Scientist, Pacific Northwest National Laboratory/ Battelle Memorial Institute
In a study for the U.S. Department of Energy, Tv broadcasting video cameras were identified as a close to-term chance for transportable direct hydrogen PEM fuel cells. A technical comparison of PEM fuel cells and competing battery alternatives was performed for Television broadcasting video cameras. The comparison involves a lifecycle expense analysis of fuel cell and battery technologies (lithium ion and nickel cadmium) below different use scenarios for Television broadcasting video cameras. A sensitivity evaluation was also performed to show the variability in typical annual technique price as individual variables (e.g. expense, durability of the fuel cell) are varied although other aspects are held continual. A worth proposition was defined for this marketplace based on the general marketplace, economic, and technology assessments.
Durability and Style of Battery/Fuel Cell Hybrid Systems
Tom Fuller, PhD, Professor, Director of the Center for Innovative Fuel Cell and Battery Technologies, Georgia Institute of Technologies
Hybrid architectures are becoming frequent regardless of the program scale. The principal aim of technique design has been minimizing fuel consumption. Whereas it is understood that the components of the system have to be evaluated and the manage strategy scrutinized simultaneously, whats missing is any consideration of the durability of the electrochemical devices. The necessity of understanding and predicting not just initial overall performance but life behavior is paramount to commercialization of these power systems. A system model elucidates the interactions amongst elements and enables the response of the program as a entire to changing load demands to be determined. Their life and the linked failure mechanisms are strongly dependent on the architecture, load profile, and manage techniques. This is illustrated with an example of platinum stability in a fuel-cell hybrid technique.
Development of a Fully-Integrated, Hybrid, High Temperature PEM Fuel Cell/Lithium Ion Battery Power Plant
Daniel A. Betts, PhD, Engineering Manager, EnerFuel, a subsidiary of Ener1, Inc.
From a business standpoint, Ener1, Inc. is nicely-positioned to take benefit of the upcoming demand for fuel cell/battery automotive power plants. Ener1 is the parent business of EnerDel, an automotive lithium-ion battery developer, and EnerFuel, a fuel cell company. While EnerDel is in the approach of establishing itself as an crucial player in the automotive lithium ion battery market, EnerFuel has been building fuel cells with substantial technical advantages more than standard automotive fuel cell technologies. EnerFuel has pioneered higher temperature PEM fuel cell stacks. High temperature operation has allowed EnerFuel to pursue styles that are tough, thermally steady, compact, and reasonably economical. In this presentation, quantifiable positive aspects of EnerFuels higher temperature PEM fuel cell are discussed.
