Nonlinear Performance Degradation Prediction of Proton Exchange Membrane Fuel Cells Using Relevance Vector Machine
Environmental issues, especially global warming due to the greenhouse effect, have become more and more critical in recent decades. As one potential candidate among different alternative “green energy” solutions for sustainable development, the proton exchange membrane fuel cell (PEMFC) has received extensive research attention for many years for energy and transportation applications. In this paper, an advanced self-adaptive relevance vector machine (RVM) has been developed and demonstrated to predict the performance degradation of PEMFCs.

Enabling Cryogenic Hydrogen-Based CO2-Free Air Transport: Meeting the Demands of Zero Carbon Aviation
Flightpath 2050 from the European Union (EU) sets ambitious targets for reducing the emissions from civil aviation that contribute to climate change. Relative to aircraft in service in year 2000, new aircraft in 2050 are to reduce CO 2 emissions by 75% and nitrogen oxide (NOx) emissions by 90% per passenger kilometer flown. While significant improvements in asset management and aircraft and propulsion-system efficiency and are foreseen, it is recognized that the Flightpath 2050 targets will not be met with conventional jet fuel.

Harnessing the Full Potential of Clean Energy: The Role of Southern California’s Utility Distributed Energy Resource Pilots
California is committed to achieving carbon neutrality to reduce the threat of climate change by 2045. This will require deep decarbonization across all economic sectors and necessitate rigorous planning to keep energy safe, reliable, and affordable. Southern California Edison (SCE), a utility that delivers electricity to 15 million people across southern, central, and coastal California, undertook an in-depth analysis to identify a feasible and economical path to realizing California’s greenhouse gas reduction goals and achieve carbon neutrality at the lowest reasonable cost by 2045.
