Optimal Design of Stamping Process for Fabrication of

Due to the high importance of metallic bipolar plates (BPPs) in proton exchange membrane fuel cell (PEMFC) from mechanical properties and ease of production points of view, titanium is selected because of its excellent corrosion resistance and low density. The present study deals with the forming of titanium ultra-thin sheet (with a thickness of 0.1 mm) as an alternative for BPPs using the

Potentially critical fabrication tolerances, such as reactant channel dimensions (4) will be identified and considered with fabrication limitations in mind. As the bipolar plate material in question may be intended for use in either hydrogen or direct methanol fuel cells, an examination of each material's ion content and leaching characteristics will be executed under appropriate conditions.

Development and Characterization of Expanded

Expanded graphite-based nanocomposites as bipolar plates for polymer electrolyte membrane fuel cells (PEMFCs) are developed by compression molding technique. The expanded graphite is prepared by chemical intercalation of 50 BS mesh particle size of natural graphite by strong acid. It is found that composite bipolar plate with a varying weight percent of resin and EG gives the high electrical

Nanomaterials, Catalysis, Electrochemistry

Other elements of a PEM fuel cell are also characterized, such as the electrolytic polymer membrane or the bipolar plates. In order to estimate the corrosion resistance of stainless steel and coated stainless steel bipolar plates and their stability in the corrosive environment of a fuel cell, corrosion tests are conducted in a Biologic corrosion cell.
