We welcome Lee Jacobsen this next Tuesday at 10 AM MDT for a webinar presentation on modeling and dynamic optimization of a solid oxide fuel cell system. The presentation will be followed by a question and answer session with a brief introduction to set the stage for the discussion.

Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic, electrolyte. Advantages of this class of fuel cells include high efficiency, long-term stability, fuel flexibility, low emissions, and relatively low cost. The largest disadvantage is the high operating temperature which results in longer start-up times and mechanical and chemical compatibility issues. To address these fundamental challenges, a nonlinear Model Predictive Control strategy was formulated to limit thermal stresses during load changes and startup procedures. The control strategy relies on a detailed mathematical model composed of partial differential algebraic equations (PDAEs). The model is posed to simultaneously converge the model equations and minimize the objective function with the large-scale nonlinear programming solver APOPT. The approach is generally applicable to any system that can be described by PDAE equations. Some of the areas covered with this presentation include: * Current state of the art in multivariate control of solid oxide fuel cells * Large-scale dynamic optimization for real time application * Nonlinear dynamic model identification and validation * Improved control techniques with next generation multivariate control strategies All Upcoming Webinars: http://apmonitor.com/wiki/index.php/Main/ApplicationWebinars Dynamic Optimization of Solid Oxide Fuel Cells July 2, 2013, 10 AM MDT Lee Jacobsen Prospects and Challenges for Olefins Production Oct 3, 2013, 9 AM MDT Panel Discussion by Mark Darby, Doug Nicholson, Judson Wooters, Richard Hughes, Brian Ashcraft Advanced Deep Water Monitoring Systems Nov 7, 2013, 4 PM MST David Brower, CEO Astro Technology, Inc.
