| Research Abstract |
In this project, elucidation of mass transport and material degradation mechanisms in polymer electrolyte fuel cells (PEFCs) by advanced diagnostics using magnetic resonance imaging (MRI) and laser techniques were performed. We developed an nuclear-labeing MRI technique to investigate water transport with and without micro porous layer in PEFCs. We also developed a visualization system of gas flow behavior in PEFC by optical absorption of Ozone. The system applied ultra violet light absorption that is characteristic of Ozone to unseeded velocity measurement and captured the shift of light absorption point. A penetration flow through porous gas diffusion layer was experimentally identified in an operating PEFC.
