Random walk simulations on proton transport in proton exchange membranes

Random walk simulations on the process of proton transport in proton exchange membranes were studied. Influences of water content and doping degree were discussed by means of a new model. Proton transport is the outcome of segmental motion and hoping of protons, which were stated in ready experimental reports. The content of two kinds of contributions to proton transport depends on the specified system of proton conductivity. The conductivity was denoted as the two forms in this paper. The results were fairly consistent with experimental results by quantity and half-quantity analysis.
