摘要：

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 co. Values of 0.40 x 10(-6) cm(2)/s and 4.98 X 10(-6) mol/cm(3) were obtained for the diffusion coefficient and solubility, respectively of the Cape Cod membrane. These values are significantly less than those of Nafion 117 tested under identical conditions. (C) 2000 The Electrochemical Society. S0013-4651(99)08-003-9. All rights reserved.
