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
Whats 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 cars battery (8V to 14 V)
• Keep H20 temperature under 921oC
• Monitor pressure in electrolysis cell
• Device does not interfere with everyday
  operations of the vehicle

9
Control System
TIs 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.

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
