  1. DH2S Fuel Cell Project 2008-2009

  2. Who We Are • Students from grades 10 - 12 • Self motivated • Different roles based on personal interests • Independent learning environment

  3. Mission Statement • Design and build a hydrogen fuel cell car • Speeds over 40 mph. • Able to accommodate drivers of any size. • Create the most efficient alternative energy vehicle possible which is a model for green energy. • An Education Center • Build Engineering skills • Build Design skills • Build skills for surviving in today’s business and industrial world. • A source for information on Alternative Energy in our Community. • Father’s Day Car Show • CTEA Conference • International Recognition of Our Fuel Cell Car • China

  4. Properties of Hydrogen • Binds easily • Very light • Rarely alone • MP is just above absolute zero • Easily ignited • Not dangerous—but must be handled carefully

  5. Fuel Cells • A fuel cell uses hydrogen and oxygen to produce electricity by splitting them into their component molecules. • Only by-product is H2O and heat • http://www.ballard.com/About_Ballard/Resources/How_Fuel_Cells_Work.htm

  6. Progress Phase 1 Phase 2 Phase 3 • A light weight aluminum frame let us conduct trial runs • Lowered center of gravity • The “Mule” or test bed served as the basis for our initial fuel cell testing. The test bed allowed us to adjust different aspects of the car and the fuel cell to suit our needs Installed batteries for electric hybrid operation

  7. Most Recent Phase Phase 4 • Hydrogen fuel cell car • Plug-in hybrid • “all integration”—statistical analysis and gather data from a pit crew • 40 mph on a flat 400 meter track • Possible for everyone in class to drive • 48 Volt Lead Acid Battery System

  8. About the Car • Battery system • Four 12 volt Lead acid batteries in series to create a 48 volt system • Fuel cell is stepped up with a 24v-48v converter to allow for recharging of the batteries for extended range • Solar panel recharging station allows the car to be completely off the grid. • Driving system • Two 48 volt hub motors • Communicate • Can achieve speeds over 40 miles per hour

  9. Electrical Engineers • Responsible for integration of fuel cell, battery recharging system, and motor control • Accomplishments: • New simplified “plug-and play” battery system. • New communicative hub motor system. • Integrated a fuse safety system Current Objectives: • Current Objectives • Rebuild a new electrical system with ultra light weight lithium ion batteries

  10. Mechanical • Accomplishments: • Hub motor driving system • New universal joint steering system • Foot pedal apparatus for both accelerating and braking. • Design so that any person can fit in the car and drive it with no extra training or experience or physical specifications. • 40 mile per hour driving. • Current Objectives: • Secure and modernize a new disc braking system • Design a new lighter aluminum frame. • Analyze all components on the car for safety when driving at speeds that exceed above 50 mph.

  11. Fabrication • Accomplishments: • Build a complicated steel frame designed so that every member of the class could drive it. • MIG Welding • Milling machine. • Learn how to effectively TIG weld aluminum • Gain experience using a plasma cutter for more accurate cuts. • Current Objectives: • Build a lighter more streamlined aluminum frame: • TIG Welding • Plasma cutter

  12. Public Relations • Must know every detail of project • Accomplishments: • Toyota Road show • Involved the entire Darien High School population • GM Fuel cell division • Worked with us, our students, and guests to educate our community further about the future of alternative energy. • Various publications • CTEA • Father’s Day Car show • Current objectives: • Continue to educate the community about alternative energy so that the popular culture can shift towards a cleaner, more efficient energy grid and transportation system.

  13. Responsible for all financial aspects of the project Reviews the budgets of the different teams Ensures that there is a sufficient amount of funds available. Organizes documentation pertaining to grants and donated money Business Manager • Accomplishments: • North East Utilities grant $2,500 • Allowed for all recent innovations on the vehicle including: • Best Buy $10,000 grant • Current Objectives: • Join Connecticut Coalition of Fuel Cells • Obtain more funding from various sources: • School budget • Various professional firms • Grants

  14. Information Technology • Responsibilities/Tasks • Purchase domain name • Research html design • Become competent with Macromedia Dreamweaver and Flash 8 • Current objectives • Website must be informative • Descriptions, diagrams • Website must be attractive • Pictures, animations • www.darienps.org/dhsfuelcell/welcome_fin.html
