HOW DO FUEL CELLS WORK?

Fuel Cells Generate ElectricityBy Freeing Electrons From H2 Gas

Because the Proton Exchange Membrane does not carry electron current,

the Freed Electrons are Forced to Follow an External Path through a Wire(Thus Generating Electrical Power)

HOW DO FUEL CELLS WORK?

Because the Proton Exchange Membrane does not carry electron current,

the Freed Electrons are Forced to Follow an External Path through a Wire(Thus Generating Electrical Power)While the H+ ions (protons) are free to travel across the membrane via

Ion Exchange Reactions!

HOW DO FUEL CELLS WORK?

While the H+ ions (protons) are free to travel across the membrane via Ion Exchange Reactions!

At the Opposite Electrode, H+ ions, O2(gas) andElectrons combine to form H2O byproducts--- Making this Technology ENVIRONMENTALLY FRIENDLY!!!

Researchers are Asking the Question---

?

H2 Fuel???

Beginning with the most Important Factors to Consider:• Safety • Cost• Supply Rate

How do we provide H2 to the Fuel Cell???

H2 Fuel???

We examine our technological options (for Automotive Applications)…• 5” Stainless Steel Tanks to Carry Gaseous Hydrogen • On-Board Production of Hydrogen from Hydrocarbons –(C-C-C)x-• Release of Hydrogen Gas from Metal Hydrides

The Dobbins’ Group has limited their studies to Metal Hydride ApproachWe are looking into…• NaAlH4 with Ti Dopants Added• LiBH4

• MgH2

Hydrogen Storage Materials---Complex Metal Hydride --- NaAlH4

Technical Questions surrounding the use of this material???

• What are the kinetics of hydrogen uptake and release?• What are the cost benefits of hydrogen fuel vs. oil? • • • Where are the Dopant (Ti) atoms within the structure? (Answer: Using Our X-ray Approaches, we will try to pinpoint the location of Ti in NaAlH4.)

X-ray Approaches

Using 2 types of X-rays

Stationary Anode X-ray Generator Synchrotron X-ray Generator

Advanced Photon Sourceat Argonne National Laboratory

Impact on 9-12 grade science education---- how will you begin to construct a learning module around this work so that 9-12 graders can become interested/involved in synchrotron x-ray work (this is specific to your science education interests and I am also interested in developing this sort of information). 

User Facilities…(What’s needed to discuss with K-12ers the need for user facilities?)
