| 英文摘要 | a series of chromium nitride films are prepared on stainless steel substrates by pulsed bias arc ion plating (pbaip) at different n(2) flow rate as bipolar plates for proton exchange membrane fuel cell (pemfc). the film chemical composition and phase structure are characterized by x-ray photoelectron spectroscopy (xps) and x-ray diffractometry (xrd). the characterization results indicate that the nitrogen content of deposited films varies from 0.28 to 0.50, and the phase structure changes from mixtures of cr + cr(2)n, pure cr(2)n through cr(2)n+crn, to pure crn. the interfacial contact resistance between samples and carbon paper is measured by wang's method, and a minimum value of 5.8 m omega cm(2) is obtained under 1.2 mpa compaction force. the anticorrosion property is examined by potentiodynamic test in the simulated corrosive circumstance of the pemfc under 25 degrees c, and the lowest corrosive current density of 5.9 x 10(-7) a cm(-2) is obtained at 0.6v (vs. sce). stainless steel substrates coated by the film with lowest contact resistance are chosen as the bipolar plates to assemble cells. an average voltage value of 0.62v is achieved at 500 ma cm(-2), which is close to that of the cell with ag-plated bipolar plates. crown copyright (c) 2009 published by elsevier b.v. all rights reserved. |
