Conductive amorphous carbon-coated 316L stainless steel as bipolar plates in polymer electrolyte membrane fuel cells

A comparison of carbon coated and uncoated 316L stainless steel for using as bipolar plates in PEMFCs

“…4. However the trend of uncoated 316L stainless steel at anodic condition is not well understand but similar trend has been reported in the literature [14,21,22].…”

“…AFM analysis was used to evaluate the morphology of the carbon film. There is a conventional method to measure interfacial contact resistance (ICR) for bipolar plates in PEMFCs [10][11][12][13][14]17,18]. In this method two pieces of carbon paper are sandwiched between the sample and two copper plates.…”

“…Recently deposition of carbon films on a metallic substrate, such as stainless steel or titanium, are proposed to be used as bipolar plates in polymer electrolyte membrane fuel cell (PEMFC) [8][9][10][11][12][13][14][15]. Bipolar plates, that are a multifunctional component, are most important parts in the PEMFC.…”

Investigation of sintered stainless steel fiber felt as gas diffusion layer in proton exchange membrane fuel cells

“…Before coating, the samples were carefully cleaned with acetone in an ultrasonic cleaner for 30 min and then dried. The a-C film was then deposited onto the samples using a CFUBMSIP system and the process parameters were well documented in our previous publications [23,24].…”

Effect of substrate temperature on structural properties and corrosion resistance of carbon thin films used as bipolar plates in polymer electrolyte membrane fuel cells

“…It seems that, carbon coating could significantly improve the corrosion resistance and the electrical conductivity. Indeed some attempts have been made to improve the performance of bipolar plates [14][15][16][17][18][19][20].…”
