fuel cell vehicles
DESCRIPTION
Jamie McBrien's IET PATW presentation describes what fuel cell vehicles are and why they being developed. The common myth regarding their safety is highlighted. Before concluding it also provides a comparison to electric vehicle performance.TRANSCRIPT
Fuelling The FutureFuel Cell Vehicle Development
By Jamie McBrien
IET Present Around the World 2014
Mechanical Engineer, Johnson Matthey Fuel Cells
Current issues
Carbon Dioxide
Nitrogen Oxides
Carbon Monoxide
Particulate matter
Other toxins
• 1bn vehicles worldwide each emit 5 tonnes of CO2 per year• Legislation for 1.5 million ZEVs on California’s roadways by 2025
What are fuel cell vehicles?Hydrogen
Storage TankPower
Control Unit
Fuel Cell Stack
Electric Motor
Fuel Cell: Hydrogen + Oxygen → WaterCombustion: Petrol + Oxygen → Water + CO2 + CO + NOx + Particles / toxins
Why are they being developed?
• Zero emissions and better efficiency
• Direct replacement for current vehicles
• Opportunity to use renewable energy
