SYSTEMS (AND DEVICES)?
3WHAT IS INTEGRATIVE NANOARCHITECTURE? ? control
of charge and mass transport through components
and across interfaces by control of nanoscale
structure and chemical composition
4Fuel Cells--Overview
Polymer/AAO Proton Exchange Membrane
Poly(ethylenimine) (PEI) in Anodized Aluminum
Oxide (AAO)
- Chemical, thermal, and structural stability
- Well suited to poly(ethylenimine)-based polymers
- Higher proton conductivity
- Confined to straight path through pores
- Ordered polymer may improve conductivity
- Anode and Cathode Layers
- Nano-textured catalyst layers
- Improved efficiency
- Non Platinum
- Improved gas diffusion
- Improved water removal (cathode)
Membrane Electrode Assembly with polymer/AAO
structure and catalyst electrodes
