How are the metallic bipolar plates used for PEM fuel cell ...

Metallic bipolar plates (BPPs) in Proton Exchange Membrane Fuel Cells (PEMFCs) offer high mechanical strength, superior electrical conductivity, and lower volume compared to graphite, enabling thinner, high-power-density stacks. Typically made of stainless steel, titanium, or aluminum, these plates require protective, conductive coatings (e.g., carbon, nitrides) to mitigate corrosion and prevent ion contamination in acidic, humid environments.

High Power Density: Metallic plates allow for thinner designs, reducing total stack volume and weight compared to graphite plates.
Mechanical Durability: They possess better mechanical strength, providing improved shock and vibration resistance for automotive applications.
Manufacturing Scalability: Suitable for high-volume production techniques like stamping, hydroforming, and roller forming.
Functionality: They effectively distribute reactant gases, manage heat, and conduct electric current between cells.

Corrosion Resistance: The acidic/humid environment can cause metal corrosion and leaching of ions (
$cap F e raised to the 3 plus power$
,
$cap C r raised to the 3 plus power$
,
$cap N i raised to the 2 plus power$
), which poisons the membrane electrode assembly (MEA).
Surface Treatment: Protective coatings, such as [Physical Vapor Deposition (PVD)] or carbon-based materials, are essential to ensure low interfacial contact resistance and high corrosion resistance.
Materials: Stainless steel is the most common, cost-effective, and manufacturable choice, while titanium is used for higher corrosion resistance.
