500h Continuous aging life test on PBI/H3PO4 high-temperature PEMFC
International Journal of Hydrogen Energy, 2006Abstract 500 h continuous aging test on high-temperature PEMFC (phosphoric acid-doped PBI system) was conducted, steady-state performance (current density = 640 mA cm - 2 ) was recorded, polarization curves were tested every 24 h, and electrochemical techniques—cyclic voltametry (CV) and electrochemical impedance spectroscopy ...

Battery aging test design during first and second life
2020 IEEE Vehicle Power and Propulsion Conference (VPPC), 2020A significant amount of retired lithium-ion car battery will be available by 2030. As an opportunity, they could be used to power less demanding applications while satisfying environmental and economic goals. Their eligibility to new applications can be assess by the means of two approaches: performing fast characterization tests or using their first ...
