  1. Electrolysis Cell

  2. The Team Shaun Ivy Joseph Jarrell Dr. Jim Harden Jason Griggs Sam Johnson

  3. Purpose • Create a device that controls and monitors the electrolysis cell • Achieve maximum performance • Reduce harmful emissions

  4. What is an O2 Sensor? • Measures the amount of oxygen in the exhaust • Analog output • Controls Air/Fuel Ratio

  5. What is an Electrolysis Cell? 2H2O O2 + 2H2 O2 + H2 Combustion

  6. What’s going on here? • The fuel cell injects hydrogen and oxygen into the vehicles combustion chamber. • The added elements allow the fuel to burn more completely allowing more energy from the same amount of gasoline. • The hydrogen and oxygen also burn generating extra fuel for increased power.

  7. Motivation Previous research has shown: • Market is essentially untapped • Gas mileage increased by up to 68% • Hydrocarbon emissions decreased by 90% • Increased horsepower

  8. Design Requirements • Conform to FCC Regulations, Class-B Device • Run off car’s battery (8V to 14 V) • Keep H20 temperature under 92±1oC • Monitor pressure in electrolysis cell • Device does not interfere with everyday operations of the vehicle

  9. Control System TI’s MSP430 Micro-controller will monitor and relay messages through the control box.

  10. TI MSP430 • Voltage Range 1.8 –3.6 • 12Bit A/D Converter • -- precision to 0.001V • 60KB of Flash Memory • -- Upper end of 32KB needed

  11. Power Conditioning Circuit • Regulates voltage coming from the car battery • Max 748A chip currently in use • Diodes protect against improper connection

  12. Software Overview

  13. Design Requirements Again • FCC regulations were followed closely. • All input voltages come directly from the vehicle battery. • A temperature sensor gauges the water temperature and halts operation if the temperature is too high. • A pressure sensor ensures pressure is maintained.

  14. Temperature Test Data

  15. Gas Mileage Test Data

  16. Gas Mileage Analysis • Based on our test data: 3000 miles / 11.94 mi/gal = 251gal 3000 miles / 34.96 mi/gal = 85.8 gal Price per gallon = $1.399/10 Cost without cell: $351.51 Cost with cell: $120.05

  17. Accomplishments • All sensors are integrated into the fuel cell and working properly. • Microcontroller code 90% written and tested. • Power conditioning circuit fully functional and tested. • Successful electrolysis cell testing
