[en] 'Full text:' The Green Energy and Fuel Cell Materials Research in Chemical Engineering at the University of Waterloo focuses on the design and performance of hydrogen fuel cell stacks and systems, including the modeling of fuel cell system reliability, and research into potential failure modes and causes experienced in hydrogen power systems. In order to adequately model fuel cell performance and reliability, an interest in both fuel cell modeling, as well reliability analysis and simulation is part of the research program. Control systems and maintenance planning over the life of a fuel cells stack must account for degradation and changes in the performance characteristics. Research includes these adaptive control systems for fuel cell and fuel cell/battery hybrid systems. Completed projects include the design of hydrogen retail stations, and hydrogen based off grid community power systems. (author)
