Multi-Gas Sensors for Enhanced Reliability of SOFC Operation DOE/NETL Cooperative Agreement: DE-FE0031653 Project kickoff Meeting, September 17, 2018 GE: Radislav Potyrailo, Joleyn Brewer, Richard St-pierre, Brian Scherer, Majid Nayeri, Andrew Shapiro SUNY Poly: Michael Carpenter, Nora Houlihan, Vitor Vulcano Rossi, Laila Banu R.A. Potyrailo 2018 2 GE PUBLIC Background Unmet need for real-time monitoring of several gases with affordable unobtrusive, cost-effective solution Real-time knowledge of several anode tail gases: • will allow control of efficiency of reforming process in the SOFC system • will deliver a lower operating cost for SOFC customers Multivariate response #1 Gas 1 Gas 2 Gas 3 $ 250K instrument Status quo: Mature traditional analytical concepts Performance need: Multi-gas discrimination Example of benchmark instrument for pilotscale optimizations: State-of-the-art system (Rosemount Analytical, Model X-STREAM) with multiple detectors: - non-dispersive infrared detectors for CO, CO2 , and CH4 gases and high levels of H2O vapor, - thermal conductivity detector for H2 , - capacitance detector for low levels of H2O vapor Required periodic recalibration to correct for drift: 2% per week (~100% drift per year) R.A. Potyrailo 2018 3 GE PUBLIC Project goal and objectives The project goal is: to build gas sensors for in situ monitoring of several gases of SOFC systems and to perform their long-term field validation tests
