Micro Proton Exchange Membrane Fuel Cell Transient Current Distribution and Product Water Measurements

In the study, the micro fuel cells were designed and fabricated in-house through a deep UV lithography technique, and a metal-organic chemical vapor deposition technique was used as microstructure material for fuel cell flow field plates. The conductive and insulating flow field plates include interdigitated, serpentine, parallel, and mesh. The experiments with several operation condition include of different cell operating temperatures, different reactant flow rates, and different operating times. This study of various operating parameters shows the physical phenomenon in the current density distribution in fuel cell reaction area and water accumulation in flow channel, and results are represented by VI curve and PI curve. The relationship of physics phenomenon between fuel cell¡¦s power production and water production rates from the current density distribution and water accumulation, can be found through visualization.
