Transcript

  • 1. Fuel Cell & Electrolysis Technology S This project is funded by NSF-1004083
  • 2. What is a Fuel Cell?S Energy conversion deviceS Various fuels & operating conditions for different applications S Hydrogen (e.g. transportation) S Methanol (e.g. portable electronics) S Microbial (e.g. wastewater treatment)S No moving parts = lower maintenanceS Efficient, quietS Better than batteries: S No need to recharge, refuel rapidly This project is funded by NSF-1004083
  • 3. Where are Fuel Cells Used?S Transportation: S Cars from automakers for the US and global markets GM: over 100 FC Equinoxes with over 2 million miles driven S Buses in Los Angeles, Chicago, Vancouver, and GermanyS Power Generation: On-site power for houses and businessesS Portable: Army testing Direct Methanol Fuel Cells for remote power This project is funded by NSF-1004083
  • 4. What is a Hydrogen Fuel Cell?S Electrochemical energy conversion: S Chemical reaction produces electricityS Hydrogen + Oxygen = ElectricityS Byproducts: S Heat S Water This project is funded by NSF-1004083
  • 5. How Does a Hydrogen Fuel Cell Work?S Anode (-): Hydrogen 𝐻2 ⟶ 2𝐻 + + 2𝑒 −S Cathode (+): Oxygen (Air) 1 𝑂2 + 2𝐻 + + 2𝑒 − ⟶ 𝐻2 𝑂 2S Overall: 1 𝐻2 + 𝑂 ⟶ 𝐻2 𝑂 2 2 This project is funded by NSF-1004083
  • 6. Hydrogen Production & Storage Hydrogen Production Hydrogen StorageS Current production: S Underground: caverns, aquifers, S fossil fuels, natural gas, and coal. and depleted petroleum and gas fields…Expensive!S Other technology: S reforming of natural gas, partial S Vehicular Pressurized Hydrogen oxidation of hydrocarbons, and coal Tanks gasification—will not help to decrease the dependence on fossil fuels S Liquid Hydrogen Storage: Beneficial for transportation andS Best: portable storage S electrolysis of water into hydrogen & oxygen—efficient but requires lots of electricity S Metal Hydride Storage This project is funded by NSF-1004083
  • 7. Electrolysis: Fuel Cell in Reverse S Same reaction as hydrogen fuel cell, only in reverse: S Supply water and electricity S Generate hydrogen & oxygen S Perfect match for hydrogen fuel cells S Issue: S Have to supply electricity S Solution: S Use solar panels or other renewable sources This project is funded by NSF-1004083
  • 8. Today’s Project:Hydrogen Fuel Cell Car This project is funded by NSF-1004083
  • 9. Today’s Project:Hydrogen Fuel Cell Car This project is funded by NSF-1004083
