Catalyst Layer
Support
 Platinum (Pt) nanoparticles used as the catalyst
 Carbon blacks (e.g., Vulcan XC-72, Acetylene Black,
Ketjen Black, etc.) are used support materials

Type of catalyst support has a dramatic effect on fuel cell performance
CATALYST SUPPORT MATERIALS- LIMITATIONS
electrochemical
instability
presence of sulfur
impurities
• loss of Pt nanoparticles or
aggregation of particles
• Pt poisoning
formation of
microporous
structure
• preventing easy access of the
reactants
presence of deep
cracks
• difficulty in the formation of
three-phase boundary
long-term degradation of the catalyst performance
CATALYST SUPPORT MATERIALS-REQUIREMENTS
Large
surface area
High
conductivity
Challanges
Development of catalysts
 minimal loading
 maximum catalytic
activity
Catalyst Support
Affinity to
Corrosion
resistant
 CO tolerance
nanoparticles  high durability
Free from
impurities
the unique structure and properties of
graphene can fullfill these requirements
OBJECTIVE
 Increase catalyst dispersion, utilization and stability
 Reduce the amount of catalyst loading in the electrodes
