Fe-based amorphous alloys as bipolar plates for PEM fuel cell

Dependency of the corrosion properties of in-situ Ti-based BMG matrix composites with the volume fraction of crystalline phase

“…Values of the potentiodynamic properties were averaged from the results of at least 3 measurements. Potentiostatic polarization tests were performed for 2 h with the identical solution, bubbling and temperature conditions as described above under a constant applied potential of À0.1V that simulate the environment encountered at the anodic side of bipolar plates used in polymer electrolyte membrane fuel cell [12,13]. After the potentiostatic polarization experiments, the samples were examined using Auger Electron Spectroscopy (AES) analysis.…”

Amorphous Alloys/Bulk Metallic Glasses (BMG)

“…Some of the few but important applications of amorphous/glassy ribbons are in transformer cores (soft and hard magnetic properties) (Chrobak et al 2006;Kane et al 2012), hydrogen membrane separators, e.g., during coal gasification (Hara et al 2002;Yamaura et al 2005), bipolar plates, and catalytic membranes in fuel cells, etc. (Fleury et al 2006;Jayalakshmi et al 2012). In order to overcome this constraint, methods to increase the thickness/dimension of the materials with slower solidification rates are developed, wherein the solidification rates involved are 10 2 -10 3 K s −1 (see Fig.…”

Corrosion Behavior of Passivated 316LSS with Ag Coating as PEMFC Bipolar Plate

“…High cost and brittleness of graphite bipolar plate limit them to large-scale applications. Therefore, many researchers aim to investigate substitute materials including carbon composite materials, light metal materials [7][8][9][10], Fe-based alloys, stainless steels [11,12], and Ni-based materials [13][14][15]. Among these alternative materials, stainless steel is a promising candidate due to its high mechanical strength, low cost, and easiness in mass production.…”
