Dr. Hong Xu

Doctoral Student | Industry: Energy - Renewable Energy - Hydrogen Fuel Cell • Investigated operando water saturation, water transport mechanism and water evaporation in porous GDL/MPL materials of PEM Fuel Cells via 4D X-ray CT imaging. • Reconstructed time-series 3D water distribution in the fuel cell and evaluated the gas diffusion properties of GDL/MPL for an improved PEFC water management strategy.

Collaborator | Industry: Manufacturing - Automotive - Green Vehicle • Collaborated with Toyota in fuel cell vehicle materials development and in charge of project experiments for investigation of novel MPL materials and water transport mode in fuel cell. • Involved in Technology and Data Transfer Project between Toyota R&D and PSI; published co-papers in fuel cell MPL investigation (JPS2019) and 4D X-ray CT imaging (ECST2019)

Working Student | Industry: Manufacturing - Electronics - Semiconductor • Evaluated chip quality and reliability at failure test station independently; specialized in failure analysis of Infineon developed semiconductor chips via thermal and electrical stress processes. • Summarized and analyzed the electronic behavior data of stressed Infineon chips, severed as a quality control process for performance optimizations.

• Designed mechanical test-stand for the split and delay line (SDL) of the ultra-fast X-ray pulse atthe European XFEL considering technical requirements under ultra-high vacuum. • Assembled the test-stand for the SDL and tested its vacuum degree, furthermore fabricated electronic cables and tested the parasitic motion of linear translation stage based on python.

• Thesis: Subsecond Operando X-ray CT of Liquid Water in Polymer Electrolyte Fuel Cells • Thesis accepted without further changes
