“…As a result of the rising cost of fossil fuels and the pressing need for environmental protection, special attention has been paid to fuel cells as viable alternative energy sources [1]. BPPs are one of the essential components in PEM fuel cells, responsible for separating cells, electrically connecting the cathode of one cell to the anode of another cell, feeding reactive gases through gas channels, and removing heat and byproducts from the fuel cell [2,3].…”

Bipolar Plates (BPPs) are the most crucial component of the Polymer Electrolyte Membrane (PEM) fuel cell system. To improve fuel cell stack performance and lifetime, corrosion resistance and Interfacial Contact Resistance (ICR) enhancement are two essential factors for metallic BPPs. One of the most effective methods to achieve this purpose is adding a thin solid film of conductive coating on the surfaces of these plates. In the present study, 410 Stainless Steel (SS) was selected as a metallic bipolar plate. The coating process was performed using titanium nitride and chromium nitride by the Cathodic Arc Evaporation (CAE) method. The main focus of this study was to select the best coating among CrN and TiN on the proposed alloy as a substrate of PEM fuel cells through the comparison technique with simultaneous consideration of corrosion resistance and ICR value. After verifying the TiN and CrN coating compound, the electrochemical assessment was conducted by the potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) tests. The results of PDP show that all coated samples have an increase in the polarization resistance (Rp) values (ranging from 410.2 to 690.6 Ω·cm2) compared to substrate 410 SS (230.1 Ω·cm2). Corrosion rate values for bare 410 SS, CrN, and TiN coatings were measured as 0.096, 0.032, and 0.060 mpy, respectively. Facilities for X-ray Diffraction (XRD), Scanning Electron Microscope (FE-SEM, TeScan-Mira III model and made in the Czech Republic), and Energy Dispersive X-ray Spectroscopy (EDXS) were utilized to perform phase, corrosion behavior, and microstructure analysis. Furthermore, ICR tests were performed on both coated and uncoated specimens. However, the ICR of the coated samples increased slightly compared to uncoated samples. Finally, according to corrosion performance results and ICR values, it can be concluded that the CrN layer is a suitable choice for deposition on 410 SS with the aim of being used in a BPP fuel cell system.

“…SOFCs have various applications, from industries to home appliances. 6,7 In a proton conducting electrolyte, protons are more mobile than oxygen ions due to their smaller size and therefore have higher conductivity, and its operating temperature can be lowered in comparison to that of oxygen ion conducting electrolytes. These types of electrolytes also show better chemical compatibility with the widely used metallic nickel catalyst anodes and therefore increase the cell efficiency.…”

In this work novel nanocomposite proton exchange membranes were prepared using sulfonated polyethersulfone (SPES) with incorporation of ZnS functionalized quantum dots (FQDs) with a solution-casting method. The effect of functionalized groups (-COOH and NH 2 ) of ZnS FQDs on the SPES membrane properties such as proton conductivity and performance was investigated. The highest proton conductivity of the nanocomposite membranes was achieved 116 mS/cm at 90 C. The nanocomposite membranes containing 2 wt% of ZnS FQDs displayed constant proton conductivity life time in 180 hours and fuel cell life time in 70 hours at 90 C, 98% RH, which confirmed strong interaction between functionalized group of ZnS FQDs and -SO 3 H groups of SPES. The power density of the SPES-ZnS FQDs nanocomposite membranes (DS of SPES: 45% and ZnS FQDs content: 2 wt%) obtained 0.53 W/cm 2 in 98% RH, 0.5 V, and 90 C. The results confirmed that the prepared nanocomposite membranes with remarkable performance can be used as useful membranes for fuel cells.
