Effect Of Impurities On Performance Of Proton Exchange Membrane Fuel Cell Components, Kitiya Hongsirikarn

All Dissertations

It is believed that proton–exchange membrane fuel cells (PEMFCs) are going to be exploited as power generation devices for stationary, automotive, and portable applications in the near future because of their high performance and environmental friendliness. Up to the present, wide spread utilization of PEMFCs is not viable because of their cost and durability in the presence of fuel and oxidant stream impurities. These impurities include NH₃, hydrocarbons, CO, CO₂, halogenated compounds, cations, etc. The objective of this research was to investigate the effect of these harmful contaminants containing in the H₂ fuel stream on …
