Comparison of Characteristics of Fluorine Doped Zinc and Gallium Tin Oxide Composite Thin Films Deposited on Stainless Steel 316 Bipolar Plate by Electron Cyclotron Resonance-Metal Organic Chemical Vapor Deposition for Proton Exchange Membrane Fuel Cells
In order to replace the brittle graphite bipolar plates currently used for the PEMFC stack, coated SUS 316 was employed. As a metallic bipolar plate, coated SUS 316 can provide higher mechanical strength, better durability to shocks and vibration, less permeability, improved thermal and bulk electrical conductivity, as well as being thinner and lighter. To enhance the interfacial contact resistance and corrosion resistance of SUS 316, the deposition of GTO:F and ZTO:F composite films was carried out by ECR-MOCVD. The surface morphology of the films consisted of tiny elliptically shaped grains with a thickness of 1 μm. The corrosion current for GTO:F was 0.13 Acm−2 which was much lower than that of bare SUS 316 (50.16 Acm−2). The GTO:F coated film had the smallest corrosion current due to the formation of a tight surface morphology with very few pin-holes. The GTO:F coated film exhibited the highest cell voltage and power density due to its lower ICR values.
