Stainless steels have received wide attention as a substitute material for bipolar plates in high temperature proton exchange membrane fuel cell(HT-PEMFc).In the present work,the crN,crAlN and multilayer crN/crAlN coatings were deposited on 316 L SS to increase the corrosion resistance and decrease the interfacial contact *** deposited coatings exhibited face centered cubic phase structure and it was verified from the X-ray diffraction pattern.X-ray photo electron spectroscopy results showed the formation of both crN and crAlN layers on 316 L ***/crAlN coating is more helpful in water management due to low surface roughness and high contact angle in the HT-PEMFc *** corrosion resistance behavior of all the samples were studied in 85%H_(3)PO_(4)solution at 140℃purged with H_(2)(HT-PEMFc anode)and O_(2)(HT-PEMFc cathode)*** results showed that all the coatings considerably improved the performance of 316 L SS and superior corrosion resistance was observed for crN/crAlN multilayer coating,whose protective efficiency was 98.12%and 96.14%in the two simulated HT-PEMFc *** results of electrochemical impedance spectroscopic studies demonstrated higher impedance for crN/crAlN *** morphological studies performed after corrosion studies revealed that protection ability of crN/crAlN coating still remained acceptable.A very low interfacial contact resistance value of 6 mΩ cm^(2) at 140 N/cm;was observed for crN/crAlN ***,after corrosion studies,the interfacial contact resistance value of crN/crAlN coated 316 L was much lower than that of crN and crAlN coatings due to the increased oxidation *** maximum power density of about 0.93 W/cm^(2) at 2 A/cm^(2) and output voltage of 0.96 V was observed for crN/crAlN coating.
