This paper describes advanced laser measurement techniques and magnetic resonance imaging (MRI) visualization for thermo-fluid engineering on fuel cell and CO_2 sequestration. MRI visualization was successfully applied to measure transversal water content distributions in a polymer electrolyte fuel cell membrane, indicating that electro-osmotic drag plays an important role on membrane dehydration. Tunable diode laser absorption spectroscopy (TDLAS) was also introduced for remote optical sensing on water vapor concentration in narrow size of fuel cell channels. Two-dimensional time-series PIV captured vortex induced vibration, simulating a flow field around a CO_2 releasing pipe in CO_2 ocean sequestration.
