Oxygen Diffusion Coefficient and Solubility in a New Proton Exchange Membrane

Abstract

The electrochemical monitoring technique is used to measure the solubility and the diffusion coefficient of oxygen in a new proton exchange membrane that is being developed by Cape Cod Research, Inc. Using the method of least squares, the data were fit to an analytical solution of Fick’s second law to determine D and c0. Values of 0.40 3 10 26 cm2/s and 4… (More)
