| Abstract Scope |
Global climate change and carbon constrained economic growth remain most influential drivers for the transitioning of the energy infrastructure to a renewable driven hydrogen economy. This presentation focuses on electrochemical technologies (fuel cells, electrolyzers, electrochemical reactors) as they offer a pathway for efficient, clean and cost effective systems implementation and integration with renewables. Performance stability and overall high systems cost are key challenges and barriers for global adoption. Challenges associated with long term performance degradation (both electrochemically active and balance of plant components) will be presented. We will examine the role of multi-constituent fuel and oxidant gases and redox atmospheres; trace gaseous contaminants; bulk, surface interface reaction products formation; on metallic and ceramic materials stability. Accelerated degradation of metallic components in the presence of H2and H2O will be analyzed, Degradation mitigation approaches will be examined. Research needs for the accelerated adoption will be proposed. |
